int gnutls_error_is_fatal(int error);
- int error
is a GnuTLS error code, a negative error code
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).
Non-zero value on fatal errors or zero on non-fatal.
