+ * 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
