/**
 * gnutls_global_set_mutex:
 * @init: mutex initialization function
 * @deinit: mutex deinitialization function
 * @lock: mutex locking function
 * @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.
 *
 * This function must be called prior to any other GnuTLS function; otherwise
 * the behavior is undefined.
 *
 * Deprecated: This function is discouraged on GnuTLS 3.7.3 or later.
 *
 * Since: 2.12.0
