These function calls appeared in 4.2BSD. Note close() releases the resource associated with a connection but does not necessarily close the connection immediately. socket.setsockopt(level, optname, value)¶ Set the value of the given socket option (see the Unix manual page setsockopt(2)).

scope is one of TIPC_ZONE_SCOPE, TIPC_CLUSTER_SCOPE, and TIPC_NODE_SCOPE. TIPC_* TIPC related constants, matching the ones exported by the C socket API. Note that exactly what is valid depends on both the value of address_family and the underlying implementation of inet_pton(). Errno.h Windows The client side will try to connect to the all addresses returned as a result of the name resolution, and sends traffic to the first one connected successfully. # Echo server

The flags argument can be one or several of the AI_* constants, and will influence how results are computed and returned.

exception socket.timeout¶ This exception is raised when a timeout occurs on a socket which has had timeouts enabled via a prior call to settimeout(). Errno 0 struct msghdr { void *msg_name; /* optional address */ socklen_t msg_namelen; /* size of address */ struct iovec *msg_iov; /* scatter/gather array */ size_t msg_iovlen; /* # elements in msg_iov */ socket.connect(address)¶ Connect to a remote socket at address. (The format of address depends on the address family -- see above.) Note This method has historically accepted a pair of parameters for MSG_DONTROUTE Don't use a gateway to send out the packet, only send to hosts on directly connected networks.

Efault Bad Address

If the AF_UNIX constant is not defined then this protocol is unsupported. SOCK_PACKET Obsolete and should not be used in new programs; see packet(7). Linux Socket Error Codes Packets are just silently dropped when a device queue overflows.) ENOMEM No memory available. Linux Errno Example exception socket.gaierror¶ This exception is raised for address-related errors, for getaddrinfo() and getnameinfo().

CONFORMING TO top POSIX.1-2001, POSIX.1-2008, 4.4BSD. his comment is here A value of None indicates that new socket objects have no timeout. EINVAL Invalid flags in type. How big can a planet be Why were Navajo code talkers used during WW2? Errno.h In C

In non-blocking mode, operations fail (with an error that is unfortunately system-dependent) if they cannot be completed immediately. socket.close()¶ Close the socket.

However, some historical (BSD) implementations required this header file, and portable applications are probably wise to include it. Ebadf If the IP address string ip_string is invalid, socket.error will be raised. An out-of-band data transmission mechanism may be supported.

The first two examples support IPv4 only. # Echo server program import socket HOST = '' # Symbolic name meaning all available interfaces PORT = 50007 # Arbitrary non-privileged port s Enoexec New in version 2.6: Linux-only support for TIPC is also available using the AF_TIPC address family.

However, it is possible that many protocols may exist, in which case a particular protocol must be specified in this manner. Join our community today! New in version 2.5. navigate here Depending on the platform, shutting down one half of the connection can also close the opposite half (e.g.

This function is rarely needed, but can be used to get or set socket options on a socket passed to a program as standard input or output (such as a server To find the fully qualified domain name, use the function getfqdn(). gethostbyaddr() supports both IPv4 and IPv6. Registration is quick, simple and absolutely free. READ ERROR if after the server close() the client does: ...

The return value is a pair (string, address) where string is a string representing the data received and address is the address of the socket sending the data.
