On Unix, it supports IP (Internet Protocol) and Unix domain sockets. On other systems, it only supports IP. Functions specific for a socket are available as methods of the socket object. Functions: socket() -- create a new socket object socketpair() -- create a pair of new socket objects [*] fromfd() -- create a socket object from an open file descriptor [*] fromshare() -- create a socket object from data received from socket.share() [*] gethostname() -- return the current hostname gethostbyname() -- map a hostname to its IP number gethostbyaddr() -- map an IP number or hostname to DNS info getservbyname() -- map a service name and a protocol name to a port number getprotobyname() -- map a protocol name (e.g. 'tcp') to a number ntohs(), ntohl() -- convert 16, 32 bit int from network to host byte order htons(), htonl() -- convert 16, 32 bit int from host to network byte order inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89) socket.getdefaulttimeout() -- get the default timeout value socket.setdefaulttimeout() -- set the default timeout value create_connection() -- connects to an address, with an optional timeout and optional source address. [*] not available on all platforms! Special objects: SocketType -- type object for socket objects error -- exception raised for I/O errors has_ipv6 -- boolean value indicating if IPv6 is supported IntEnum constants: AF_INET, AF_UNIX -- socket domains (first argument to socket() call) SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument) Integer constants: Many other constants may be defined; these may be used in calls to the setsockopt() and getsockopt() methods. éN)Ú*)ÚIntEnumÚIntFlagÚEBADFé ÚEAGAINé Ú EWOULDBLOCKÚfromfdÚgetfqdnÚcreate_connectionÚ create_serverÚhas_dualstack_ipv6Ú AddressFamilyÚ SocketKindcCs| ¡o| d¡S)NZAF_©ÚisupperÚ startswith©ÚC©rú/usr/lib64/python3.8/socket.pyÚLórcCs| ¡o| d¡S)NZSOCK_rrrrrrQrZMsgFlagcCs| ¡o| d¡S)NZMSG_rrrrrrVrZ AddressInfocCs| ¡o| d¡S)NZAI_rrrrrr[rz 127.0.0.1z::1cCs(z ||ƒWStk r"|YSXdS)z{Convert a numeric family value to an IntEnum member.

By passing None as the value of host and port, you can pass NULL to the underlying C API.
