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 [*] 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) ssl() -- secure socket layer support (only available if configured) 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 Integer constants: AF_INET, AF_UNIX -- socket domains (first argument to socket() call) SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument) Many other constants may be defined; these may be used in calls to the setsockopt() and getsockopt() methods. i����N( t *( t partial( t MethodTypec C s5 d d l } t j d t d d �| j | | | � S( Ni����s; socket.ssl() is deprecated.

Convenience function. Connect to *address* (a 2-tuple ``(host, port)``) and return the socket object. Passing the optional *timeout* parameter will set the timeout on the socket instance before attempting to connect. If no *timeout* is supplied, the global default timeout setting returned by :func:`getdefaulttimeout` is used. If *source_address* is set it must be a tuple of (host, port) for the socket to bind as a source address before making the connection. A host of '' or port 0 tells the OS to use the default. i s! getaddrinfo returns an empty listN( RN t getaddrinfoRh t sockett _GLOBAL_DEFAULT_TIMEOUTR7 R, R- R& RZ ( t addresst timeoutt source_addresst hostt portt errt rest aft socktypeRV t canonnamet saR t _( ( s /usr/lib64/python2.7/socket.pyR s( (< Re t _sockett functoolsR t typesR t _sslt ImportErrorRN R R t sslerrorR R R R R R R R R R R R t ost sysR t cStringIOR t errnoRR R R t __all__R� t _get_exports_listR� RO t platformt lowert startswithR R| R t _socketmethodsR( RP t objectRD RK Rj t _mt pRG t mRQ t SocketTypeR_ R� R ( ( ( s /usr/lib64/python2.7/socket.pyt <module>- s� L $ , � -
