@deftypefun {void} {gnutls_global_set_mutex} (mutex_init_func @var{init}, mutex_deinit_func @var{deinit}, mutex_lock_func @var{lock}, mutex_unlock_func @var{unlock})

@var{init}: mutex initialization function

@var{deinit}: mutex deinitialization function

@var{lock}: mutex locking function

@var{unlock}: mutex unlocking function

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.

@strong{Since:} 2.12.0
