gnutls_error_is_fatal — Returns non-zero in case of a fatal error
#include <gnutls/gnutls.h>
int
gnutls_error_is_fatal( |
int | error); |
If a function returns a negative value you may feed that value to this function to see if it is fatal. Returns 1 for a fatal error 0 otherwise. However you may want to check the error code manually, since some non−fatal errors to the protocol may be fatal for you (your program).
This is only useful if you are dealing with errors from the record layer or the handshake layer.
For positive error
values, 0 is returned.
