NAME
       gnutls_global_init - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_global_init( void);

ARGUMENTS
	void

DESCRIPTION
       This  function  performs any required precalculations, detects the sup‐
       ported CPU capabilities and initializes	the  underlying	 cryptographic
       backend.	 In  order to free any resources taken by this call you should
       gnutls_global_deinit() when gnutls usage is no longer needed.

       This    function	   increments	 a    global	counter,    so	  that
       gnutls_global_deinit()  only releases resources when it has been called
       as many times as gnutls_global_init().  This is useful when  GnuTLS  is
       used  by more than one library in an application.  This function can be
       called many times, but will only do something the first time.

       Note!  This function is not thread safe.	  If  two  threads  call  this
       function	 simultaneously,  they	can  cause a race between checking the
       global counter and incrementing it, causing both threads to execute the
       library	initialization	code.	That  would lead to a memory leak.  To
       handle this, your application could invoke this function after aquiring
       a thread mutex.	To ignore the potential memory leak is also an option.

RETURNS
       On  success,  GNUTLS_E_SUCCESS  (0)  is	returned, otherwise a negative
       error code is returned.
