       gnutls_error_is_fatal - Returns non-zero in case of a fatal error


       #include <gnutls/gnutls.h>

       int gnutls_error_is_fatal(int error);


       int error   is a GnuTLS error code, a negative value


       If  a  GnuTLS function returns a negative value you may feed that value
       to this function to see if the error condition is fatal.

       Note that you may want to check the error  code  manually,  since  some
       non-fatal errors to the protocol may be fatal for you program.

       This  function  is  only useful if you are dealing with errors from the
       record layer or the handshake layer.


       1 if the error code is fatal, for positive error values, 0 is returned.
       For unknown error values, -1 is returned.
