-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

-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.

-#
-# ``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.

-#                   [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``

-# ``${CMAKE_CURRENT_BINARY_DIR}/target.list``

-#                   [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``.

-#   extract_symbols("lib.symbols"
-#     HEADERS_LIST "headers_target"

-# 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 !
