+Coding Style Conventions
+========================
+
+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 [1] with one
+excecption, we use 4 spaces instead of tabs. This closely matches what most
+libssh developers use already anyways, with a few exceptions as mentioned
+below.
+
+To shorthen this 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 whitespaces
+
+* 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?
+
+Editors
+========
+
+VIM
+----
+
+set ts=4 sw=4 et cindent
+
+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.\+/'

-Please read the file 'SubmittingPatches' 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!

-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)))
-
-
-Vim
-----
-
-For the basic vi editor included with all variants of \*nix, add the
-following to $HOME/.vimrc:
-
-    set ts=4 sw=4 et cindent
-
-You can use the Vim gitmodline plugin to store this in the git config:
-
-    http://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...*/
-
-Indention & 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");

-        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.

-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
-in the mbedTLS documentation.

-# Why?
-
-Why not ? :) I've began to work on my own implementation of the ssh protocol
-because i didn't like the currently public ones.
-Not any allowed you to import and use the functions as a powerful library,
-and so i worked on a library-based SSH implementation which was non-existing
-in the free and open source software world.

-# How/Who?
-
-If you downloaded this file, you must know what it is : a library for
-accessing ssh client services through C libraries calls in a simple manner.
-Everybody can use this software under the terms of the LGPL - see the COPYING

 How to contribute a patch to libssh
 ====================================
 
-Please checkout the libssh source code using git. Change the code and then
-use  "git format-patch" to create a patch. The patch should be signed (see
-below) and send it to libssh@libssh.org, or attach it to a bug report at
+Simple, just make the code change, and email it as either a "diff -u"
+change, or as a "git format-patch" change against the original source
+code to libssh@libssh.org, or attach it to a bug report at
 https://red.libssh.org/

-# 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`` as its output.
-#
-# The helper function ``get_files_list()`` is provided to find files given a
-# name pattern. It defines a custom command which sets ``target_name`` as its
-# output.
-#
-# Functions provided
-# ------------------
-#
-# ::
-#
-#   generate_map_file(target_name
-#                     RELEASE_NAME_VERSION release_name
-#                     SYMBOLS symbols_target
-#                     [CURRENT_MAP cur_map]
-#                     [FINAL]
-#                     [BREAK_ABI]
-#                     [COPY_TO output]
-#                    )
-#
-# ``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"
-#                     RELEASE_NAME_VERSION "lib_1_0_0"
-#                     SYMBOLS symbols
-#                    )
-#
-# 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
-# ``${CMAKE_CURRENT_BINARY_DIR}/lib.map`` containing the provided symbols.
-#
-# ::
-#
-#   get_files_list(target_name
-#                   DIRECTORIES dir1 [dir2 ...]
-#                   FILES_PATTERNS exp1 [exp2 ...]
-#                   [COPY_TO output]
-#                  )
-#
-# ``target_name``:
-#   Required, expects the name of the target to be created. A file named as
-#   ``${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}/${target_name}.list``
-#
-# Example:
-#
-# .. code-block:: cmake
-#
-#   find_package(ABIMap)
-#   get_files_list(target
-#     DIRECTORIES "/include/mylib"
-#     FILES_PATTERNS "*.h"
-#     COPY_TO "my_list.txt"
-#   )
-#
-# Consider that ``/include/mylib`` contains 3 files, ``h1.h``, ``h2.h``, and
-# ``h3.hpp``
-#
-# Will result in a file ``my_list.txt`` containing::
-#
-#   ``h1.h;h2.h``
-#
-# And the target ``target`` will have its property ``LIST_FILE`` set to contain
-# ``${CMAKE_CURRENT_BINARY_DIR}/target.list``
-#
-# ::
-#
-#   extract_symbols(target_name
-#                   HEADERS_LIST headers_list_target
-#                   [FILTER_PATTERN pattern]
-#                   [COPY_TO output]
-#                  )
-#
-# ``target_name``:
-#   Required, expects the name of the target to be created. A file named after
-#   the string given in ``target_name`` will be created in
-#   ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of symbols.
-#
-# ``HEADERS_LIST``:
-#   Required, expects a target with the property ``LIST_FILE`` set, containing a
-#   file path. Such file must contain a list of files paths.
-#
-# ``FILTER_PATTERN``:
-#   Optional, expects a string. Only the lines containing the filter pattern
-#   will be considered.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the file containing
-#   the found symbols will be copied.
-#
-# This command extracts the symbols from the files listed in
-# ``headers_list`` and write them on the ``output`` file. If ``pattern``
-# is provided, then only the lines containing the string given in ``pattern``
-# will be considered. It is recommended to provide a ``FILTER_PATTERN`` to mark
-# the lines containing exported function declaration, since this function is
-# experimental and can return wrong symbols when parsing the header files. A
-# target named ``target_name`` will be created with the property ``LIST_FILE``
-# set to contain ``${CMAKE_CURRENT_BINARY_DIR}/${target_name}.list``.
-#
-# Example:
-#
-# .. code-block:: cmake
-#
-#   find_package(ABIMap)
-#   extract_symbols("lib.symbols"
-#     HEADERS_LIST "headers_target"
-#     FILTER_PATTERN "API_FUNCTION"
-#   )
-#
-# Where ``LIST_FILE`` property in ``headers_target`` points to a file
-# containing::
-#
-#   header1.h;header2.h
-#
-# Where ``header1.h`` contains::
-#
-#   API_FUNCTION int exported_func1(int a, int b);
-#
-# ``header2.h`` contains::
-#
-#   API_FUNCTION int exported_func2(int a);
-#
-#   int private_func2(int b);
-#
-# Will result in a file ``lib.symbols.list`` in ``${CMAKE_CURRENT_BINARY_DIR}``

-# 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 
    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
 
+libgcrypt 1.6 and bigger backend does not support custom callback. Using anything else than pthreads (ssh_threads_get_pthread()) here will fail.
 Good luck !
