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.
