NAME

       gnutls_error_is_fatal - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_error_is_fatal(int error);

ARGUMENTS

       int error   is a GnuTLS error code, a negative error code

DESCRIPTION

       If  a  GnuTLS  function  returns  a  negative  error  code you may feed that value to this
       function to see if the  error  condition  is  fatal  to  a  TLS  session  (i.e.,  must  be
       terminated).

       Note  that you may also want to check the error code manually, since some non-fatal errors
       to the protocol (such as a warning alert or a rehandshake request) may be fatal  for  your
       program.

       This  function is only useful if you are dealing with errors from functions that relate to
       a TLS session (e.g., record layer or handshake layer handling functions).

RETURNS

       Non-zero value on fatal errors or zero on non-fatal.
