gnutls_global_init(3)		     gnutls		   gnutls_global_init(3)

NAME
     gnutls_global_init - API function

SYNOPSIS
     #include <gnutls/gnutls.h>

     int gnutls_global_init( void);

ARGUMENTS
      void

DESCRIPTION
     Since  GnuTLS  3.3.0  this function is no longer necessary to be explicitly
     called. To disable the implicit call (in a  library  constructor)	of  this
     function set the environment variable GNUTLS_NO_IMPLICIT_INIT to 1.

     This  function performs any required precalculations, detects the supported
     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.  It  is  thread  safe  since  GnuTLS
     3.3.0.

     A	subsequent  call  of this function if the initial has failed will return
     the same error code.

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