All details are explained here ...

http://api.libssh.org/master/libssh_tutor_threads.html

* 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.
