NAME         top

       gnutls_global_set_mutex - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void gnutls_global_set_mutex(mutex_init_func init, mutex_deinit_func
       deinit, mutex_lock_func lock, mutex_unlock_func unlock);

ARGUMENTS         top

       mutex_init_func init
                   mutex initialization function

       mutex_deinit_func deinit
                   mutex deinitialization function

       mutex_lock_func lock
                   mutex locking function

       mutex_unlock_func unlock
                   mutex unlocking function

DESCRIPTION         top

       With this function you are allowed to override the default mutex
       locks used in some parts of gnutls and dependent libraries. This
       function should be used if you have complete control of your program
       and libraries.  Do not call this function from a library, or
       preferably from any application unless really needed to. GnuTLS will
       use the appropriate locks for the running system.

       Note that since the move to implicit initialization of GnuTLS on
       library load, calling this function will deinitialize the library,
       and re-initialize it after the new locking functions are set.

       This function must be called prior to any other gnutls function.
