-# How to contribute a patch to libssh
-
-Please checkout the libssh source code using git.
-
-For contributions we prefer Merge Requests on Gitlab:
-
-https://gitlab.com/libssh/libssh-mirror/
-
-This way you get continuous integration which runs the complete libssh
-testsuite for you.
-
-For larger code changes, breaking the changes up into a set of simple
-patches, each of which does a single thing, are much easier to review.
-Patch sets like that will most likely have an easier time being merged
-into the libssh code than large single patches that make lots of
-changes in one large diff.
-
-Also bugfixes and new features should be covered by tests. We use the cmocka
-and cwrap framework for our testing and you can simply run it locally by
-calling `make test`.
-
-## Ownership of the contributed code
-
-libssh is a project with distributed copyright ownership, which means
-we prefer the copyright on parts of libssh to be held by individuals
-rather than corporations if possible. There are historical legal
-reasons for this, but one of the best ways to explain it is that it's
-much easier to work with individuals who have ownership than corporate
-legal departments if we ever need to make reasonable compromises with
-people using and working with libssh.
-
-We track the ownership of every part of libssh via https://git.libssh.org,
-our source code control system, so we know the provenance of every piece
-of code that is committed to libssh.
-
-So if possible, if you're doing libssh changes on behalf of a company
-who normally owns all the work you do please get them to assign
-personal copyright ownership of your changes to you as an individual,
-that makes things very easy for us to work with and avoids bringing
-corporate legal departments into the picture.
-
-If you can't do this we can still accept patches from you owned by
-your employer under a standard employment contract with corporate
-copyright ownership. It just requires a simple set-up process first.
-
-We use a process very similar to the way things are done in the Linux
-Kernel community, so it should be very easy to get a sign off from
-your corporate legal department. The only changes we've made are to
-accommodate the license we use, which is LGPLv2 (or later) whereas the
-Linux kernel uses GPLv2.
-
-The process is called signing.
-
-## How to sign your work
-
-Once you have permission to contribute to libssh from your employer, simply
-email a copy of the following text from your corporate email address to:
-
-contributing@libssh.org
-
-
-```
-libssh Developer's Certificate of Origin. Version 1.0
-
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the appropriate
-    version of the GNU General Public License; or
-
-(b) The contribution is based upon previous work that, to the best of
-    my knowledge, is covered under an appropriate open source license
-    and I have the right under that license to submit that work with
-    modifications, whether created in whole or in part by me, under
-    the GNU General Public License, in the appropriate version; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a) or (b) and I have not modified it.
-
-(d) I understand and agree that this project and the contribution are
-    public and that a record of the contribution (including all
-    metadata and personal information I submit with it, including my
-    sign-off) is maintained indefinitely and may be redistributed
-    consistent with the libssh Team's policies and the requirements of
-    the GNU GPL where they are relevant.
-
-(e) I am granting this work to this project under the terms of the
-    GNU Lesser General Public License as published by the
-    Free Software Foundation; either version 2.1 of
-    the License, or (at the option of the project) any later version.
-
-    https://www.gnu.org/licenses/lgpl-2.1.html
-```
-
-We will maintain a copy of that email as a record that you have the
-rights to contribute code to libssh under the required licenses whilst
-working for the company where the email came from.
-
-Then when sending in a patch via the normal mechanisms described
-above, add a line that states:
-
-    Signed-off-by: Random J Developer <random@developer.example.org>
-
-using your real name and the email address you sent the original email
-you used to send the libssh Developer's Certificate of Origin to us
-(sorry, no pseudonyms or anonymous contributions.)
-
-That's it! Such code can then quite happily contain changes that have
-copyright messages such as:
-
-    (c) Example Corporation.
-
-and can be merged into the libssh codebase in the same way as patches
-from any other individual. You don't need to send in a copy of the
-libssh Developer's Certificate of Origin for each patch, or inside each
-patch. Just the sign-off message is all that is required once we've
-received the initial email.
-
-
-# Coding conventions in the libssh tree
-
-## Quick Start
-
-Coding style guidelines are about reducing the number of unnecessary
-reformatting patches and making things easier for developers to work together.
-
-You don't have to like them or even agree with them, but once put in place we
-all have to abide by them (or vote to change them).  However, coding style
-should never outweigh coding itself and so the guidelines described here are
-hopefully easy enough to follow as they are very common and supported by tools
-and editors.
-
-The basic style for C code, is the Linux kernel coding style (See
-Documentation/CodingStyle in the kernel source tree). This closely matches what
-libssh developers use already anyways, with a few exceptions as mentioned
-below.
-
-But to save you the trouble of reading the Linux kernel style guide, here
-are the highlights.
-
-* Maximum Line Width is 80 Characters
-  The reason is not about people with low-res screens but rather sticking
-  to 80 columns prevents you from easily nesting more than one level of
-  if statements or other code blocks.
-
-* Use 4 Spaces to Indent
-
-* No Trailing Whitespace
-  Clean up your files before committing.
-
-* Follow the K&R guidelines.  We won't go through all of them here. Do you
-  have a copy of "The C Programming Language" anyways right?
-
-
-## Editor Hints
-
-### Emacs
-
-Add the follow to your $HOME/.emacs file:
-
-    (add-hook 'c-mode-hook
-      (lambda ()
-          (c-set-style "linux")
-          (c-toggle-auto-state)))
-
-
-## Neovim/VIM
-
-For the basic vi editor included with all variants of \*nix, add the
-following to ~/.config/nvim/init.rc or ~/.vimrc:
-
-    set ts=4 sw=4 et cindent
-
-You can use the Vim gitmodline plugin to store this in the git config:
-
-https://git.cryptomilk.org/projects/vim-gitmodeline.git/
-
-For Vim, the following settings in $HOME/.vimrc will also deal with
-displaying trailing whitespace:
-
-    if has("syntax") && (&t_Co > 2 || has("gui_running"))
-        syntax on
-        function! ActivateInvisibleCharIndicator()
-            syntax match TrailingSpace "[ \t]\+$" display containedin=ALL
-            highlight TrailingSpace ctermbg=Red
-        endf
-        autocmd BufNewFile,BufRead * call ActivateInvisibleCharIndicator()
-    endif
-    " Show tabs, trailing whitespace, and continued lines visually
-    set list listchars=tab:»·,trail:·,extends:…
-
-    " highlight overly long lines same as TODOs.
-    set textwidth=80
-    autocmd BufNewFile,BufRead *.c,*.h exec 'match Todo /\%>' . &textwidth . 'v.\+/'
-
-
-## FAQ & Statement Reference
-
-### Comments
-
-Comments should always use the standard C syntax.  C++ style comments are not
-currently allowed.
-
-The lines before a comment should be empty. If the comment directly belongs to
-the following code, there should be no empty line after the comment, except if
-the comment contains a summary of multiple following code blocks.
-
-This is good:
-
-    ...
-    int i;
-
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-
-    /* This is a one line comment about i = 5. */
-    i = 5;
-
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /**
-     * @brief This is a doxygen comment.
-     *
-     * This is a more detailed explanation of
-     * this simple function.
-     *
-     * @param[in]   param1     The parameter value of the function.
-     *
-     * @param[out]  result1    The result value of the function.
-     *
-     * @return              0 on success and -1 on error.
-     */
-    int example(int param1, int *result1);
-
-This is bad:
-
-    ...
-    int i;
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-    /* This is a one line comment about i = 5. */
-    i = 5;
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /*This is a one line comment.*/
-
-    /* This is a multi line comment,
-       with some more words...*/
-
-    /*
-     * This is a multi line comment,
-     * with some more words...*/
-
-### Indentation & Whitespace & 80 columns
-
-To avoid confusion, indentations have to be 4 spaces. Do not use tabs!.  When
-wrapping parameters for function calls, align the parameter list with the first
-parameter on the previous line.  For example,
-
-    var1 = foo(arg1,
-               arg2,
-               arg3);
-
-The previous example is intended to illustrate alignment of function
-parameters across lines and not as encourage for gratuitous line
-splitting.  Never split a line before columns 70 - 79 unless you
-have a really good reason.  Be smart about formatting.
-
-
-### If, switch, & Code blocks
-
-Always follow an 'if' keyword with a space but don't include additional
-spaces following or preceding the parentheses in the conditional.
-This is good:
-
-    if (x == 1)
-
-This is bad:
-
-    if ( x == 1 )
-
-or
-
-    if (x==1)
-
-Yes we have a lot of code that uses the second and third form and we are trying
-to clean it up without being overly intrusive.
-
-Note that this is a rule about parentheses following keywords and not
-functions.  Don't insert a space between the name and left parentheses when
-invoking functions.
-
-Braces for code blocks used by for, if, switch, while, do..while, etc.  should
-begin on the same line as the statement keyword and end on a line of their own.
-You should always include braces, even if the block only contains one
-statement.  **NOTE**: Functions are different and the beginning left brace should
-be located in the first column on the next line.
-
-If the beginning statement has to be broken across lines due to length, the
-beginning brace should be on a line of its own.
-
-The exception to the ending rule is when the closing brace is followed by
-another language keyword such as else or the closing while in a do..while loop.
-
-Good examples:
-
-    if (x == 1) {
-        printf("good\n");
-    }
-
-    for (x = 1; x < 10; x++) {
-        print("%d\n", x);
-    }
-
-    for (really_really_really_really_long_var_name = 0;
-         really_really_really_really_long_var_name < 10;
-         really_really_really_really_long_var_name++)
-    {
-        print("%d\n", really_really_really_really_long_var_name);
-    }
-
-    do {
-        printf("also good\n");
-    } while (1);
-
-Bad examples:
-
-    while (1)
-    {
-        print("I'm in a loop!\n"); }
-
-    for (x=1;
-         x<10;
-         x++)
-    {
-        print("no good\n");
-    }
-
-    if (i < 10)
-        print("I should be in braces.\n");
-
-
-### Goto
-
-While many people have been academically taught that "goto"s are fundamentally
-evil, they can greatly enhance readability and reduce memory leaks when used as
-the single exit point from a function. But in no libssh world what so ever is a
-goto outside of a function or block of code a good idea.
-
-Good Examples:
-
-    int function foo(int y)
-    {
-        int *z = NULL;
-        int rc = 0;
-
-        if (y < 10) {
-            z = malloc(sizeof(int)*y);
-            if (z == NULL) {
-                rc = 1;
-                goto done;
-            }
-        }
-
-        print("Allocated %d elements.\n", y);
-
-    done:
-        if (z != NULL) {
-            free(z);
-        }
-
-        return rc;
-    }
-
-### Initialize pointers
-
-All pointer variables **MUST** be initialized to `NULL`. History has
-demonstrated that uninitialized pointer variables have lead to various
-bugs and security issues.
-
-Pointers **MUST** be initialized even if the assignment directly follows
-the declaration, like pointer2 in the example below, because the
-instructions sequence may change over time.
-
-Good Example:
-
-    char *pointer1 = NULL;
-    char *pointer2 = NULL;
-
-    pointer2 = some_func2();
-
-    ...
-
-    pointer1 = some_func1();
-
-### Typedefs
-
-libssh tries to avoid `typedef struct { .. } x_t;` so we do always try to use
-`struct x { .. };`. We know there are still such typedefs in the code, but for
-new code, please don't do that anymore.
-
-### Make use of helper variables
-
-Please try to avoid passing function calls as function parameters in new code.
-This makes the code much easier to read and it's also easier to use the "step"
-command within gdb.
-
-Good Example:
-
-    char *name;
-
-    name = get_some_name();
-    if (name == NULL) {
-        ...
-    }
-
-    rc = some_function_my_name(name);
-    ...
-
-
-Bad Example:
-
-    rc = some_function_my_name(get_some_name());
-    ...
-
-Please try to avoid passing function return values to if- or while-conditions.
-The reason for this is better handling of code under a debugger.
-
-Good example:
-
-    x = malloc(sizeof(short) * 10);
-    if (x == NULL) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-Bad example:
-
-    if ((x = malloc(sizeof(short)*10)) == NULL ) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-There are exceptions to this rule. One example is walking a data structure in
-an iterator style:
-
-    while ((opt = poptGetNextOpt(pc)) != -1) {
-        ... do something with opt ...
-    }
-
-But in general, please try to avoid this pattern.
-
-
-### Control-Flow changing macros
-
-Macros like `STATUS_NOT_OK_RETURN` that change control flow (return/goto/etc)
-from within the macro are considered bad, because they look like function calls
-that never change control flow. Please do not introduce them.
-
-### Switch/case indentation
-
-The `case` should not be indented to avoid wasting too much horizontal space.
-When the case block contains local variables that need to be wrapped in braces,
-they should not be indented again either.

+    cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ..
     make
 
-On Windows you should choose a makefile generator with -G or use
-
-    cmake-gui.exe ..
-
-To enable additional client tests against a local OpenSSH server, add the
-compile option -DCLIENT_TESTING=ON. These tests require an OpenSSH
-server package and some wrapper libraries (see optional requirements) to
-be installed.
-
-If you're interested in server testing, then a OpenSSH client should be
-installed on the system and if possible also dropbear. Once that is done
-enable server support with -DWITH_SERVER=ON and enable testing of it with
--DSERVER_TESTING=ON.

-Please read the file 'CONTRIBUTING.md' next to this README file. It explains
-our copyright policy and how you should send patches for upstream inclusion.
+Changes between 0.4 and 0.5
+---------------------------
+
+We use the ssh_ prefix as namespace for every function now. There is a legacy.h
+which could be used to get the old function names.
+
+Changes between 0.3 and 0.4
+---------------------------
+
+We changed libssh to be typesafe now:
+
+SSH_SESSION *session -> ssh_session session
+SFTP_SESSION *sftp -> sftp_session sftp
+CHANNEL *channel -> ssh_channel channel
+STRING *string -> ssh_string string
+...
+
+The options structure has been removed and there is a new function. This
+function can set all available options now. You can find the enum in the
+header file and it is documented. Example:
+
+ssh_options_set(session, SSH_OPTIONS_HOST, "localhost");
+
+5* Copyright policy
+-_-_-_-_-_-_-_-_-_-_
+
+libssh is a project with distributed copyright ownership, which means we prefer
+the copyright on parts of libssh to be held by individuals rather than
+corporations if possible. There are historical legal reasons for this, but one
+of the best ways to explain it is that it’s much easier to work with
+individuals who have ownership than corporate legal departments if we ever need
+to make reasonable compromises with people using and working with libssh.
+
+We track the ownership of every part of libssh via git, our source code control
+system, so we know the provenance of every piece of code that is committed to
+libssh.
+
+So if possible, if you’re doing libssh changes on behalf of a company who
+normally owns all the work you do please get them to assign personal copyright
+ownership of your changes to you as an individual, that makes things very easy
+for us to work with and avoids bringing corporate legal departments into the
+picture.
+
+If you can’t do this we can still accept patches from you owned by your
+employer under a standard employment contract with corporate copyright
+ownership. It just requires a simple set-up process first.
+
+We use a process very similar to the way things are done in the Linux Kernel
+community, so it should be very easy to get a sign off from your corporate
+legal department. The only changes we’ve made are to accommodate the license we
+use, which is LGPLv2 (or later) whereas the Linux kernel uses GPLv2.
+
+The process is called signing.
+
+How to sign your work
+----------------------
+
+Once you have permission to contribute to libssh from your employer, simply
+email a copy of the following text from your corporate email address to:
+
+contributing@libssh.org
+
+--------------------------------------------------------------------------
+libssh Developer's Certificate of Origin. Version 1.0
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the appropriate
+    version of the GNU General Public License; or
+
+(b) The contribution is based upon previous work that, to the best of
+    my knowledge, is covered under an appropriate open source license
+    and I have the right under that license to submit that work with
+    modifications, whether created in whole or in part by me, under
+    the GNU General Public License, in the appropriate version; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a) or (b) and I have not modified it.
+
+(d) I understand and agree that this project and the contribution are
+    public and that a record of the contribution (including all
+    metadata and personal information I submit with it, including my
+    sign-off) is maintained indefinitely and may be redistributed
+    consistent with the libssh Team's policies and the requirements of
+    the GNU GPL where they are relevant.
+
+(e) I am granting this work to this project under the terms of the
+    GNU Lesser General Public License as published by the
+    Free Software Foundation; either version 2.1 of
+    the License, or (at the option of the project) any later version.
+
+http://www.gnu.org/licenses/lgpl-2.1.html
+--------------------------------------------------------------------------
+
+We will maintain a copy of that email as a record that you have the rights to
+contribute code to libssh under the required licenses whilst working for the
+company where the email came from.
+
+Then when sending in a patch via the normal mechanisms described above, add a
+line that states:
+
+
+   Signed-off-by: Random J Developer <random@developer.example.org>
+
+
+using your real name and the email address you sent the original email you used
+to send the libssh Developer’s Certificate of Origin to us (sorry, no
+pseudonyms or anonymous contributions.)
+
+That’s it! Such code can then quite happily contain changes that have copyright
+messages such as:
+
+
+   (c) Example Corporation.
+
+
+and can be merged into the libssh codebase in the same way as patches from any
+other individual. You don’t need to send in a copy of the libssh Developer’s
+Certificate of Origin for each patch, or inside each patch. Just the sign-off
+message is all that is required once we’ve received the initial email.
 
 Have fun and happy libssh hacking!

-mbedTLS and libssh in multithreaded applications
-==================================================
-
-To use libssh with mbedTLS in a multithreaded application, mbedTLS has to be
-built with threading support enabled.
-
-If threading support is not available and multi threading is used, ssh_init
-will fail.
-
-More information about building mbedTLS with threading support can be found

-#
-# CHANGES:
-#
-# 2012-01-31, Lars Bilke
-# - Enable Code Coverage
-#
-# 2013-09-17, Joakim Söderberg
-# - Added support for Clang.
-# - Some additional usage instructions.
-#
-# 2016-02-03, Lars Bilke
-# - Refactored functions to use named parameters
-#
-# 2017-06-02, Lars Bilke
-# - Merged with modified version from github.com/ufz/ogs
-#
-# 2019-05-06, Anatolii Kurotych
-# - Remove unnecessary --coverage flag
-#
-# 2019-12-13, FeRD (Frank Dana)
-# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
-#   of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
-# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
-# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
-# - Set lcov basedir with -b argument
-# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
-#   overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
-# - Delete output dir, .info file on 'make clean'
-# - Remove Python detection, since version mismatches will break gcovr
-# - Minor cleanup (lowercase function names, update examples...)
-#
-# 2019-12-19, FeRD (Frank Dana)
-# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
-#
-# 2020-01-19, Bob Apthorpe
-# - Added gfortran support
-#
-# 2020-02-17, FeRD (Frank Dana)
-# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
-#   in EXCLUDEs, and remove manual escaping from gcovr targets
-#
-# 2021-01-19, Robin Mueller
-# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
-# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
-#   flags to the gcovr command
-#
-# 2020-05-04, Mihchael Davis
-#     - Add -fprofile-abs-path to make gcno files contain absolute paths
-#     - Fix BASE_DIRECTORY not working when defined
-#     - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
-#
-# 2021-05-10, Martin Stump
-#     - Check if the generator is multi-config before warning about non-Debug builds
-#
-# 2022-02-22, Marko Wehle
-#     - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
-#       This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
-#
-# 2022-09-28, Sebastian Mueller
-#     - fix append_coverage_compiler_flags_to_target to correctly add flags
-#     - replace "-fprofile-arcs -ftest-coverage" with "--coverage" (equivalent)
-#
-# USAGE:
-#
-# 1. Copy this file into your cmake modules path.
-#
-# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
-#    using a CMake option() to enable it just optionally):
-#      include(CodeCoverage)
-#
-# 3. Append necessary compiler flags for all supported source files:
-#      append_coverage_compiler_flags()
-#    Or for specific target:
-#      append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
-#
-# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
-#
-# 4. If you need to exclude additional directories from the report, specify them
-#    using full paths in the COVERAGE_EXCLUDES variable before calling
-#    setup_target_for_coverage_*().
-#    Example:
-#      set(COVERAGE_EXCLUDES
-#          '${PROJECT_SOURCE_DIR}/src/dir1/*'
-#          '/path/to/my/src/dir2/*')
-#    Or, use the EXCLUDE argument to setup_target_for_coverage_*().
-#    Example:
-#      setup_target_for_coverage_lcov(
-#          NAME coverage
-#          EXECUTABLE testrunner
-#          EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
-#
-# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
-#     relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
-#     Example:
-#       set(COVERAGE_EXCLUDES "dir1/*")
-#       setup_target_for_coverage_gcovr_html(
-#           NAME coverage
-#           EXECUTABLE testrunner
-#           BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
-#           EXCLUDE "dir2/*")
-#
-# 5. Use the functions described below to create a custom make target which
-#    runs your test executable and produces a code coverage report.
-#
-# 6. Build a Debug build:
-#      cmake -DCMAKE_BUILD_TYPE=Debug ..
-#      make
-#      make my_coverage_target
-#

-# This file provides functions to generate the symbol version script. It uses

-#   $ pip install abimap
-#
-# The ``function generate_map_file`` generates a symbol version script

-#
-# The experimental function ``extract_symbols()`` is provided as a simple

-# followed by an opening '``(``'. It is recommended to use a filter pattern to
-# select the lines to be considered. It defines a custom command which sets

-#                    )
-#
-# ``target_name``:
-#   Required, expects the name of the file to receive the generated symbol
-#   version script. It should be added as a dependency for the library. Use the
-#   linker option ``--version-script filename`` to add the version information
-#   to the symbols when building the library.
-#
-# ``RELEASE_NAME_VERSION``:
-#   Required, expects a string containing the name and version information to be
-#   added to the symbols in the format ``lib_name_1_2_3``.
-#
-# ``SYMBOLS``:
-#   Required, expects a target with the property ``LIST_FILE`` containing a path
-#   to a file containing the list of symbols to be added to the symbol version
-#   script.
-#
-# ``CURRENT_MAP``:
-#   Optional. If given, the new set of symbols will be checked against the
-#   ones contained in the ``cur_map`` file and updated properly. If an
-#   incompatible change is detected and ``BREAK_ABI`` is not defined, the build
-#   will fail.
-#
-# ``FINAL``:
-#   Optional. If given, will provide the ``--final`` option to ``abimap`` tool,
-#   which will mark the modified release in the symbol version script with a
-#   special comment, preventing later changes. This option should be set when
-#   creating a library release and the resulting map file should be stored with
-#   the source code.
-#
-# ``BREAK_ABI``:
-#   Optional. If provided, will use ``abimap`` ``--allow-abi-break`` option, which
-#   accepts incompatible changes to the set of symbols. This is necessary if any
-#   previously existing symbol were removed.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the generated
-#   map file will be copied.
-#
-# Example:
-#
-# .. code-block:: cmake
-#
-#   find_package(ABIMap)
-#   generate_map_file("lib.map"

-# Where the target ``symbols`` has its property ``LIST_FILE`` set to the path to
-# a file containing::
-#
-#  ``symbol1``
-#  ``symbol2``
-#
-# This example would result in the symbol version script to be created in
-# ``${CMAKE_CURRENT_BINARY_DIR}/lib.map`` containing the provided symbols.

-# ``target_name``:
-#   Required, expects the name of the target to be created. A file named as
-#   ``${target_name}.list`` will be created in
-#   ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of files found.
-#
-# ``DIRECTORIES``:
-#   Required, expects a list of directories paths. Only absolute paths are
-#   supported.
-#
-# ``FILES_PATTERN``:
-#   Required, expects a list of matching expressions to find the files to be
-#   considered in the directories.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the file containing
-#   the list of files will be copied.
-#
-# This command searches the directories provided in ``DIRECTORIES`` for files
-# matching any of the patterns provided in ``FILES_PATTERNS``. The obtained list
-# is written to the path specified by ``output``. A target named ``target_name``
-# will be created and its property ``LIST_FILE`` will be set to contain
-# ``${CMAKE_CURRENT_BINARY_DIR}/${target_name}.list``
-#
-# Example:
-#
-# .. code-block:: cmake
-#
-#   find_package(ABIMap)
-#   get_files_list(target
-#     DIRECTORIES "/include/mylib"
-#     FILES_PATTERNS "*.h"

-#   )
-#
-# Consider that ``/include/mylib`` contains 3 files, ``h1.h``, ``h2.h``, and
-# ``h3.hpp``
-#
-# Will result in a file ``my_list.txt`` containing::

-#   Required, expects the name of the target to be created. A file named after
-#   the string given in ``target_name`` will be created in
-#   ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of symbols.
-#
-# ``HEADERS_LIST``:
-#   Required, expects a target with the property ``LIST_FILE`` set, containing a
-#   file path. Such file must contain a list of files paths.
-#
-# ``FILTER_PATTERN``:
-#   Optional, expects a string. Only the lines containing the filter pattern
-#   will be considered.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the file containing
-#   the found symbols will be copied.
-#
-# This command extracts the symbols from the files listed in
-# ``headers_list`` and write them on the ``output`` file. If ``pattern``

-# experimental and can return wrong symbols when parsing the header files. A
-# target named ``target_name`` will be created with the property ``LIST_FILE``
-# set to contain ``${CMAKE_CURRENT_BINARY_DIR}/${target_name}.list``.

-#
-# .. code-block:: cmake

-#     HEADERS_LIST "headers_target"

-# Where ``LIST_FILE`` property in ``headers_target`` points to a file

-#
-#   header1.h;header2.h
-#
-# Where ``header1.h`` contains::
-#
-#   API_FUNCTION int exported_func1(int a, int b);
-#
-# ``header2.h`` contains::
-#
-#   API_FUNCTION int exported_func2(int a);
-#
-#   int private_func2(int b);
-#

-1. Introduction
-
-This document describes the key exchange method curve25519-sha256@libssh.org
-for SSH version 2 protocol. It is provided as an alternative to the existing
-key exchange mechanisms based on either Diffie-Hellman or Elliptic Curve Diffie-
-Hellman [RFC5656].
-The reason is the following : During summer of 2013, revelations from ex-
-consultant at NSA Edward Snowden gave proof that NSA willingly inserts backdoors
-into software, hardware components and published standards. While it is still
-believed that the mathematics behind ECC cryptography are still sound and solid,
-some people (including Bruce Schneier [SCHNEIER]), showed their lack of confidence
-in NIST-published curves such as nistp256, nistp384, nistp521, for which constant
-parameters (including the generator point) are defined without explanation. It
-is also believed that NSA had a word to say in their definition. These curves
-are not the most secure or fastest possible for their key sizes [DJB], and
-researchers think it is possible that NSA have ways of cracking NIST curves.
-It is also interesting to note that SSH belongs to the list of protocols the NSA
-claims to be able to eavesdrop. Having a secure replacement would make passive
-attacks much harder if such a backdoor exists.
-
-However an alternative exists in the form of Curve25519. This algorithm has been
-proposed in 2006 by DJB [Curve25519]. Its main strengths are its speed, its
-constant-time run time (and resistance against side-channel attacks), and its
-lack of nebulous hard-coded constants.
-
-The reference version being used in this document is the one described in
-[Curve25519] as implemented in the library NaCl [NaCl].
-This document does not attempt to provide alternatives to the ecdsa-sha1-*
-authentication keys.
-
-2. Key exchange
-
-The key exchange procedure is very similar to the one described chapter 4 of
-[RFC5656]. Public ephemeral keys are transmitted over SSH encapsulated into
-standard SSH strings.
-
-The following is an overview of the key exchange process:
-
-Client                                                            Server
-------                                                            ------
-Generate ephemeral key pair.
-SSH_MSG_KEX_ECDH_INIT          -------->
-                                            Verify that client public key
-                                            length is 32 bytes.
-                                             Generate ephemeral key pair.
-                                                   Compute shared secret.
-                                         Generate and sign exchange hash.
-                               <--------           SSH_MSG_KEX_ECDH_REPLY
-Verify that server public key length is 32 bytes.
-* Verify host keys belong to server.
-Compute shared secret.
-Generate exchange hash.
-Verify server's signature.
-
-*   Optional but strongly recommended as this protects against MITM attacks.
-
-This is implemented using the same messages as described in RFC5656 chapter 4
-
-3. Method Name
-
-The name of this key exchange method is "curve25519-sha256@libssh.org".
-
-4. Implementation considerations
-
-The whole method is based on the curve25519 scalar multiplication. In this
-method, a private key is a scalar of 256 bits, and a public key is a point
-of 256 bits.
-
-4.1. Private key generation
-
-A 32 bytes private key should be generated for each new connection,
- using a secure PRNG. The following actions must be done on the private key:
-     mysecret[0] &= 248;
-     mysecret[31] &= 127;
-     mysecret[31] |= 64;
-In order to keep the key valid. However, many cryptographic libraries will do
-this automatically.
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the result is a valid and secure private key.
-
-4.2 Public key generation
-
-The 32 bytes public key of either a client or a server must be generated using
-the 32 bytes private key and a common generator base. This base is defined as 9
-followed by all zeroes:
-     const unsigned char basepoint[32] = {9};
-
-The public key is calculated using the cryptographic scalar multiplication:
-     const unsigned char privkey[32];
-     unsigned char pubkey[32];
-     crypto_scalarmult (pubkey, privkey, basepoint);
-However some cryptographic libraries may provide a combined function:
-     crypto_scalarmult_base (pubkey, privkey);
-
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the received public keys are valid curves point. The
-Curve25519 algorithm ensure that every possible public key maps to a valid
-ECC Point.
-
-4.3 Shared secret generation
-
-The shared secret, k, is defined in SSH specifications to be a big integer.
-This number is calculated using the following procedure:
-
-     X is the 32 bytes point obtained by the scalar multiplication of the other
-     side's public key and the local private key scalar.
-
-     The whole 32 bytes of the number X are then converted into a big integer k.
-     This conversion follows the network byte order. This step differs from
-     RFC5656.

-/**
-@page libssh_tutor_pkcs11 Chapter 9: Authentication using PKCS #11 URIs
-@section how_to How to use PKCS #11 URIs in libssh?
-
-PKCS #11 is a Cryptographic Token Interface Standard that provides an API
-to devices like smart cards that store cryptographic private information.
-Such cryptographic devices are referenced as tokens. A mechanism through which
-objects stored on the tokens can be uniquely identified is called PKCS #11 URI
-(Uniform Resource Identifier) and is defined in RFC 7512
-(https://tools.ietf.org/html/rfc7512).
-
-# Pre-requisites (OpenSSL < 3.0):
-
-OpenSSL 1.x defines an abstract layer called the "engine" to achieve
-cryptographic acceleration. The engine_pkcs11 module acts like an interface
-between the PKCS #11 modules and the OpenSSL application.
-
-To build and use libssh with PKCS #11 support:
-1. Enable the cmake option: $ cmake -DWITH_PKCS11_URI=ON
-2. Build with OpenSSL.
-3. Install and configure engine_pkcs11 (https://github.com/OpenSC/libp11).
-4. Plug in a working smart card or configure softhsm (https://www.opendnssec.org/softhsm).
-
-@warning The support for Engines was deprecated in OpenSSL 3.0 so this approach
-is deprecated in libssh 0.11.x.
-
-# Pre-requisites (OpenSSL 3.0.8+)
-
-The OpenSSL 3.0 is deprecating usage of low-level engines in favor of high-level
-"providers" to provide alternative implementation of cryptographic operations
-or acceleration.
-
-To build and use libssh with PKCS #11 support using OpenSSL providers:
-1. Install and configure pkcs11 provider (https://github.com/latchset/pkcs11-provider).
-2. Enable the cmake options: $ cmake -DWITH_PKCS11_URI=ON -DWITH_PKCS11_PROVIDER=ON
-3. Build with OpenSSL.
-4. Plug in a working smart card or configure softhsm (https://www.opendnssec.org/softhsm).
-
-# New API functions
-
-The functions  ssh_pki_import_pubkey_file() and ssh_pki_import_privkey_file() that
-import the public and private keys from files respectively are now modified to support
-PKCS #11 URIs. These functions automatically detect if the provided filename is a file path
-or a PKCS #11 URI (when it begins with "pkcs11:"). If a PKCS #11 URI is detected,
-the engine is loaded and initialized. Through the engine, the private/public key
-corresponding to the PKCS #11 URI are loaded from the PKCS #11 device.
-
-If you wish to authenticate using public keys on your own, follow the steps mentioned under
-"Authentication with public keys" in Chapter 2 - A deeper insight into authentication.
-
-The function pki_uri_import() is used to populate the public/private ssh_key from the
-engine with PKCS #11 URIs as the look up.
-
-Here is a minimalistic example of public key authentication using PKCS #11 URIs:
-
-@code
-int authenticate_pkcs11_URI(ssh_session session)
-{
-  int rc;
-  char priv_uri[1042] = "pkcs11:token=my-token;object=my-object;type=private?pin-value=1234";
-
-  rc = ssh_options_set(session, SSH_OPTIONS_IDENTITY, priv_uri);
-  assert_int_equal(rc, SSH_OK)
-
-  rc = ssh_userauth_publickey_auto(session, NULL, NULL);
-
-  if (rc == SSH_AUTH_ERROR)
-  {
-     fprintf(stderr, "Authentication with PKCS #11 URIs failed: %s\n",
-       ssh_get_error(session));
-     return SSH_AUTH_ERROR;
-  }
-
-  return rc;
-}
-@endcode
-
-@subsection Caveats
-
-We recommend the users to provide a specific PKCS #11 URI so that it matches only a single slot in the engine.
-If the engine discovers multiple slots that could potentially contain the private keys referenced
-by the provided PKCS #11 URI, the engine will not try to authenticate.
-
-For testing, the SoftHSM PKCS#11 library is used.

-
-@section sftp_aio_api The SFTP asynchronous I/O
-
-NOTE : Please read @ref libssh_tutor_sftp before reading this page. The
-synchronous sftp_read() and sftp_write() have been described there.
-
-SFTP AIO stands for "SFTP Asynchronous Input/Output". This API contains
-functions which perform async read/write operations on remote files.
-
-File transfers performed using the asynchronous sftp aio API can be
-significantly faster than the file transfers performed using the synchronous
-sftp read/write API (see sftp_read() and sftp_write()).
-
-The sftp aio API functions are divided into two categories :
-  - sftp_aio_begin_*() [see sftp_aio_begin_read(), sftp_aio_begin_write()]:
-    These functions send a request for an i/o operation to the server and
-    provide the caller an sftp aio handle corresponding to the sent request.
-
-  - sftp_aio_wait_*() [see sftp_aio_wait_read(), sftp_aio_wait_write()]:
-    These functions wait for the server response corresponding to a previously
-    issued request. Which request ? the request corresponding to the sftp aio
-    handle supplied by the caller to these functions.
-
-Conceptually, you can think of the sftp aio handle as a request identifier.
-
-Technically, the sftp_aio_begin_*() functions dynamically allocate memory to
-store information about the i/o request they send and provide the caller a
-handle to this memory, we call this handle an sftp aio handle.
-
-sftp_aio_wait_*() functions use the information stored in that memory (handled
-by the caller supplied sftp aio handle) to identify a request, and then they
-wait for that request's response. These functions also release the memory
-handled by the caller supplied sftp aio handle (except when they return
-SSH_AGAIN).
-
-sftp_aio_free() can also be used to release the memory handled by an sftp aio
-handle but unlike the sftp_aio_wait_*() functions, it doesn't wait for a
-response. This should be used to release the memory corresponding to an sftp
-aio handle when some failure occurs. An example has been provided at the
-end of this page to show the usage of sftp_aio_free().
-
-To begin with, this tutorial will provide basic examples that describe the
-usage of sftp aio API to perform a single read/write operation.
-
-The later sections describe the usage of the sftp aio API to obtain faster file
-transfers as compared to the transfers performed using the synchronous sftp
-read/write API.
-
-On encountering an error, the sftp aio API functions set the sftp and ssh
-errors just like any other libssh sftp API function. These errors can be
-obtained using sftp_get_error(), ssh_get_error() and ssh_get_error_code().
-The code examples provided on this page ignore error handling for the sake of
-brevity.
-
-@subsection sftp_aio_read Using the sftp aio API for reading (a basic example)
-
-For performing an async read operation on a sftp file (see sftp_open()),
-the first step is to call sftp_aio_begin_read() to send a read request to the
-server. The caller is provided an sftp aio handle corresponding to the sent
-read request.
-
-The second step is to pass a pointer to this aio handle to
-sftp_aio_wait_read(), this function waits for the server response which
-indicates the success/failure of the read request. On success, the response
-indicates EOF or contains the data read from the sftp file.
-
-The following code example shows how a read operation can be performed
-on an sftp file using the sftp aio API.
-
-@code
-ssize_t read_chunk(sftp_file file, void *buf, size_t to_read)
-{
-    ssize_t bytes_requested, bytes_read;
-
-    // Variable to store an sftp aio handle
-    sftp_aio aio = NULL;
-
-    // Send a read request to the sftp server
-    bytes_requested = sftp_aio_begin_read(file, to_read, &aio);
-    if (bytes_requested == SSH_ERROR) {
-        // handle error
-    }
-
-    // Here its possible that (bytes_requested < to_read) as specified in
-    // the function documentation of sftp_aio_begin_read()
-
-    // Wait for the response of the read request corresponding to the
-    // sftp aio handle stored in the aio variable.
-    bytes_read = sftp_aio_wait_read(&aio, buf, to_read);
-    if (bytes_read == SSH_ERROR) {
-        // handle error
-    }
-
-    return bytes_read;

-
-@subsection sftp_aio_write Using the sftp aio API for writing (a basic example)
-
-For performing an async write operation on a sftp file (see sftp_open()),
-the first step is to call sftp_aio_begin_write() to send a write request to
-the server. The caller is provided an sftp aio handle corresponding to the
-sent write request.
-
-The second step is to pass a pointer to this aio handle to
-sftp_aio_wait_write(), this function waits for the server response which
-indicates the success/failure of the write request.
-
-The following code example shows how a write operation can be performed on an
-sftp file using the sftp aio API.
-
-@code
-ssize_t write_chunk(sftp_file file, void *buf, size_t to_write)
-{
-    ssize_t bytes_requested, bytes_written;
-
-    // Variable to store an sftp aio handle

-        // handle error

-@subsection sftp_aio_actual_use Using the sftp aio API to speed up a transfer
-
-The above examples were provided to introduce the sftp aio API.
-This is not how the sftp aio API is intended to be used, because the
-above usage offers no advantage over the synchronous sftp read/write API
-which does the same thing i.e issue a request and then immediately wait for
-its response.
-
-The facility that the sftp aio API provides is that the user can do
-anything between issuing a request and getting the corresponding response.
-Any number of operations can be performed after calling sftp_aio_begin_*()
-[which issues a request] and before calling sftp_aio_wait_*() [which waits
-for a response]
-
-The code can leverage this feature by calling sftp_aio_begin_*() multiple times
-to issue multiple requests before calling sftp_aio_wait_*() to wait for the
-response of an earlier issued request. This approach will keep a certain number
-of requests outstanding at the client side.
-
-After issuing those requests, while the client code does something else (for
-example waiting for an outstanding request's response, processing an obtained
-response, issuing another request or any other operation the client wants
-to perform), at the same time :
-
-  - Some of those outstanding requests may be travelling over the
-    network towards the server.
-
-  - Some of the outstanding requests may have reached the server and may
-    be queued for processing at the server side.
-
-  - Some of the outstanding requests may have been processed and the
-    corresponding responses may be travelling over the network towards the
-    client.
-
-  - Some of the responses corresponding to the outstanding requests may
-    have already reached the client side.
-
-Clearly in this case, operations that the client performs and operations
-involved in transfer/processing of a outstanding request can occur in
-parallel. Also, operations involved in transfer/processing of two or more
-outstanding requests may also occur in parallel (for example when one request
-travels to the server, another request's response may be incoming towards the
-client). Such kind of parallelism makes the overall transfer faster as compared
-to a transfer performed using the synchronous sftp read/write API.
-
-When the synchronous sftp read/write API is used to perform a transfer,
-a strict sequence is followed:
-
-  - The client issues a single read/write request.
-  - Then waits for its response.
-  - On obtaining the response, the client processes it.
-  - After the processing ends, the client issues the next read/write request.
-
-A file transfer performed in this manner would be slower than the case where
-multiple read/write requests are kept outstanding at the client side. Because
-here at any given time, operations related to transfer/processing of only one
-request/response pair occurs. This is in contrast to the multiple outstanding
-requests scenario where operations related to transfer/processing of multiple
-request/response pairs may occur at the same time.
-
-Although it's true that keeping multiple requests outstanding can speed up a
-transfer, those outstanding requests come at a cost of increased memory
-consumption both at the client side and the server side. Hence care must be
-taken to use a reasonable limit for the number of requests kept outstanding.
-
-The further sections provide code examples to show how uploads/downloads
-can be performed using the sftp aio API and the concept of outstanding requests
-discussed in this section. In those code examples, error handling has been
-ignored and at some places pseudo code has been used for the sake of brevity.
-
-The complete code for performing uploads/downloads using the sftp aio API,
-can be found at https://gitlab.com/libssh/libssh-mirror/-/tree/master.

-@subsection sftp_aio_cap Capping applied by the sftp aio API
-
-Before the code examples for uploads and downloads, its important
-to know about the capping applied by the sftp aio API.
-
-sftp_aio_begin_read() caps the number of bytes the caller can request
-to read from the remote file. That cap is the value of the max_read_length
-field of the sftp_limits_t returned by sftp_limits(). Say that cap is LIM
-and the caller passes x as the number of bytes to read to
-sftp_aio_begin_read(), then (assuming no error occurs) :
-
-  - if x <= LIM, then sftp_aio_begin_read() will request the server
-    to read x bytes from the remote file, and will return x.
-
-  - if x > LIM, then sftp_aio_begin_read() will request the server
-    to read LIM bytes from the remote file and will return LIM.
-
-Hence to request server to read x bytes (> LIM), the caller would have
-to call sftp_aio_begin_read() multiple times, typically in a loop and
-break out of the loop when the summation of return values of the multiple
-sftp_aio_begin_read() calls becomes equal to x.
-
-For the sake of simplicity, the code example for download in the upcoming
-section would always ask sftp_aio_begin_read() to read x <= LIM bytes,
-so that its return value is guaranteed to be x, unless an error occurs.
-
-Similarly, sftp_aio_begin_write() caps the number of bytes the caller
-can request to write to the remote file. That cap is the value of
-max_write_length field of the sftp_limits_t returned by sftp_limits().
-Say that cap is LIM and the caller passes x as the number of bytes to
-write to sftp_aio_begin_write(), then (assuming no error occurs) :
-
-  - if x <= LIM, then sftp_aio_begin_write() will request the server
-    to write x bytes to the remote file, and will return x.
-
-  - if x > LIM, then sftp_aio_begin_write() will request the server
-    to write LIM bytes to the remote file and will return LIM.
-
-Hence to request server to write x bytes (> LIM), the caller would have
-to call sftp_aio_begin_write() multiple times, typically in a loop and
-break out of the loop when the summation of return values of the multiple
-sftp_aio_begin_write() calls becomes equal to x.
-
-For the sake of simplicity, the code example for upload in the upcoming
-section would always ask sftp_aio_begin_write() to write x <= LIM bytes,
-so that its return value is guaranteed to be x, unless an error occurs.

-# that style
-A plain, more modern HTML style for Doxygen
-
-## Requirements
-- Doxygen (tested with version 1.8.13)
-- *optional*: a sass/scss compiler if you want to modify the style
-
-## Simple usage
-Tell Doxygen about the files for that style as shown in [doxyfile.conf](doxyfile.conf). You might need to adjust the
-paths depending on where you installed that style.
-When you run Doxygen, all files are copied into to generated HTML folder. So you don't need to keep the originals around
-unless you want to re-generate the documentation.
-
-## Advanced
-that style uses a custom javascript to hack some nice stripes into some tables. It has to be loaded from HTML. Hence you need
-to use the provided custom header. Since its default content may change when Doxygen is updated, there might be syntax error in
-the generated HTML. If this is the case, you can remove the custom header (adjust your doxyfile.conf). This has no
-disadvantages other than removing the stripes.
-
-[that_style.css](that_style.css) was generated from the scss files in the folder [sass](sass). If you want to change the style,
-use those files in order to have better control. For instance, you can easily change most colors by modifying the variables
-in the beginning of [that_style.scss](sass/that_style.scss).

 @section threads_with_libssh How to use libssh with threads
 
 libssh may be used in multithreaded applications, but under several conditions :
- - Your system must support libpthread or, in Windows environment,
-   CriticalSection based mutex control.
- - Since version 0.8.0, threads initialization is called automatically in the
-   library constructor if libssh is dynamically linked. This means it is no
-   longer necessary to call ssh_init()/ssh_finalize().
- - If libssh is statically linked, threading must be initialized by calling
-   ssh_init() before using any of libssh provided functions. This initialization
-   must be done outside of any threading context. Don't forget to call
-   ssh_finalize() to avoid memory leak
+ - Threading must be initialized during the initialization of libssh. This 
+   initialization must be done outside of any threading context.
+ - If pthreads is being used by your application (or your framework's backend),
+   you must link with libssh_threads dynamic library and initialize 
+   threading with the ssh_threads_pthreads threading object.
+ - If an other threading library is being used by your application, you must 
+   implement all the methods of the ssh_threads_callbacks_struct structure
+   and initialize libssh with it.
  - At all times, you may use different sessions inside threads, make parallel
    connections, read/write on different sessions and so on. You *cannot* use a
-   single session (or channels for a single session) in several threads at the same
+   single session (or channels for a single session) in several threads at the same 
    time. This will most likely lead to internal state corruption. This limitation is
    being worked out and will maybe disappear later.
-
+   
 @subsection threads_init Initialization of threads
 
-Since version 0.8.0, it is no longer necessary to call ssh_init()/ssh_finalize()
-if libssh is dynamically linked.
+To initialize threading, you must first select the threading model you want to
+use, using ssh_threads_set_callbacks(), then call ssh_init().
 
-If libssh is statically linked, call ssh_init() before using any of libssh
-provided functions.
+@code 
+#include <libssh/callbacks.h>
+...
+ssh_threads_set_callbacks(ssh_threads_get_noop());
+ssh_init();
+@endcode
+
+ssh_threads_noop is the threading structure that does nothing. It's the
+threading callbacks being used by default when you're not using threading.
 
 @subsection threads_pthread Using libpthread with libssh
 
-Since version 0.8.0, libpthread is the default threads library used by libssh.
+If your application is using libpthread, you may simply use the libpthread
+threading backend:
 
-To use libpthread, simply link it to you application.
+@code
+#include <libssh/callbacks.h>
+...
+ssh_threads_set_callbacks(ssh_threads_get_pthread());
+ssh_init();
+@endcode
+
+However, you must be sure to link with the library ssh_threads. If 
+you're using gcc, you must use the commandline
+@code
+gcc -o output input.c -lssh -lssh_threads
+@endcode 
 
-If you are using libssh statically linked, don't forget to call ssh_init()
-before using any of libssh provided functions (and ssh_finalize() in  the end).
 
 @subsection threads_other Using another threading library
 
-Since version 0.8.0, libssh does not support custom threading libraries.
-The change makes sense since the newer versions for libcrypto (OpenSSL) and
-libgcrypt don't support custom threading libraries.
-
-The default used threading library is libpthread.
-Alternatively, in Windows environment, CriticalSection based mutex control can
-be used.
-
-If your system does not support libpthread nor CriticalSection based mutex
-control, unfortunately, you cannot use libssh in multithreaded scenarios.
+You must find your way in the ssh_threads_callbacks_struct structure. You must
+implement the following methods :
+- mutex_lock
+- mutex_unlock
+- mutex_init
+- mutex_destroy
+- thread_id
 
 Good luck !
