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_EXPLICIT_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.

       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.
