Inaddr_any value
Webint socket (int domain, int type, int protocol) Used to create a new socket, returns a file descriptor for the socket or -1 on error. It takes three parameters: domain: the protocol family of socket being requested type: the type of socket within that family and the protocol. WebIn the simulator, INADDR_ANYhas the following semantics: When receiving, a socket bound to this address receives packets from allinterfaces. For example, suppose that a host has interfaces 0, 1 and 2. If a UDP socket on this host is bound using INADDR_ANYand udp port 8000, then the socket will receive all packets for port 8000 that arrive

WebFor IPv4 addresses, two special forms are accepted instead of a host address: '' represents INADDR_ANY, which is used to bind to all interfaces, and the string '' represents INADDR_BROADCAST. This behavior is not compatible with IPv6, therefore, you may want to avoid these if you intend to support IPv6 with your Python programs. Webshould be copied from the in6addr_anyvariable which has in6_addrtype. In static initializations, IN6ADDR_ANY_INIT may also be used, which expands to a constant expression. Both of them are in network byte order. The IPv6 loopback address (::1) is available in the global in6addr_loopbackvariable. For initializations,
