Catch Socket Error Python


They are generally used in arguments to the setsockopt() and getsockopt() methods of socket objects. This behavior is not compatible with IPv6, therefore, you may want to avoid these if you intend to support IPv6 with your Python programs. This is usually only needed for sockets opened in "raw" mode (SOCK_RAW); for the normal socket modes, the correct protocol is chosen automatically if the protocol is omitted or zero.
