NAME

6       gnutls_error_is_fatal - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_error_is_fatal(int error);
12

ARGUMENTS

14       int error   is a GnuTLS error code, a negative error code
15

DESCRIPTION

17       If  a  GnuTLS  function returns a negative error code you may feed that
18       value to this function to see if the error condition is fatal to a  TLS
19       session (i.e., must be terminated).
20
21       Note  that  you  may  also want to check the error code manually, since
22       some non-fatal errors to the protocol (such as a  warning  alert  or  a
23       rehandshake request) may be fatal for your program.
24
25       This  function is only useful if you are dealing with errors from func‐
26       tions that relate to a TLS session (e.g.,  record  layer  or  handshake
27       layer handling functions).
28

RETURNS

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