gnutls_error_is_fatal(3) gnutls gnutls_error_is_fatal(3)

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.
