NAME
       gnutls_global_init - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_global_init( void);

ARGUMENTS
	void

DESCRIPTION
       This function initializes the global data to defaults.  In order to free resources you may call gnutls_global_deinit() when gnutls usage is
       no longer needed.

       Note that this function will also initialize the underlying crypto backend, if it has not been initialized before.

       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.
