SilcBool silc_mutex_alloc(SilcMutex *mutex);

    Allocates SILC Mutex object.  The mutex object must be allocated
    before it can be used.  It is freed by the silc_mutex_free function.
    This returns TRUE and allocated mutex in to the `mutex' and FALSE
    on error.  If threads support is not compiled in this returns FALSE,
    but should not be considered as an error.
