5 | This module provides an interface to Berkeley socket IPC.
6 |
7 | Limitations:
8 |
9 | - Only AF_INET, AF_INET6 and AF_UNIX address families are supported in a
10 | portable manner, though AF_PACKET, AF_NETLINK and AF_TIPC are supported
11 | under Linux.
12 | - No read/write operations (use sendall/recv or makefile instead).
13 | - Additional restrictions apply on some non-Unix platforms (compensated
14 | for by socket.py).
15 |
16 | Module interface:
17 |
18 | - socket.error: exception raised for socket specific errors
19 | - socket.gaierror: exception raised for getaddrinfo/getnameinfo errors,
20 | a subclass of socket.error
21 | - socket.herror: exception raised for gethostby* errors,
22 | a subclass of socket.error
23 | - socket.gethostbyname(hostname) --> host IP address (string: 'dd.dd.dd.dd')
24 | - socket.gethostbyaddr(IP address) --> (hostname, [alias, ...], [IP addr, ...])
25 | - socket.gethostname() --> host name (string: 'spam' or 'spam.domain.com')
26 | - socket.getprotobyname(protocolname) --> protocol number
27 | - socket.getservbyname(servicename[, protocolname]) --> port number
28 | - socket.getservbyport(portnumber[, protocolname]) --> service name
29 | - socket.socket([family[, type [, proto, fileno]]]) --> new socket object
30 | (fileno specifies a pre-existing socket file descriptor)
31 | - socket.socketpair([family[, type [, proto]]]) --> (socket, socket)
32 | - socket.ntohs(16 bit value) --> new int object
33 | - socket.ntohl(32 bit value) --> new int object
34 | - socket.htons(16 bit value) --> new int object
35 | - socket.htonl(32 bit value) --> new int object
36 | - socket.getaddrinfo(host, port [, family, socktype, proto, flags])
37 | --> List of (family, socktype, proto, canonname, sockaddr)
38 | - socket.getnameinfo(sockaddr, flags) --> (host, port)
39 | - socket.AF_INET, socket.SOCK_STREAM, etc.: constants from <socket.h>
40 | - socket.has_ipv6: boolean value indicating if IPv6 is supported
41 | - socket.inet_aton(IP address) -> 32-bit packed IP representation
42 | - socket.inet_ntoa(packed IP) -> IP address string
43 | - socket.getdefaulttimeout() -> None | float
44 | - socket.setdefaulttimeout(None | float)
45 | - an Internet socket address is a pair (hostname, port)
46 | where hostname can be anything recognized by gethostbyname()
47 | (including the dd.dd.dd.dd notation) and port is in host byte order
48 | - where a hostname is returned, the dd.dd.dd.dd notation is used
49 | - a UNIX domain socket address is a string specifying the pathname
50 | - an AF_PACKET socket address is a tuple containing a string
51 | specifying the ethernet interface and an integer specifying
52 | the Ethernet protocol number to be received. For example:
53 | ("eth0",0x1234). Optional 3rd,4th,5th elements in the tuple
54 | specify packet-type and ha-type/addr.
55 | - an AF_TIPC socket address is expressed as
56 | (addr_type, v1, v2, v3 [, scope]); where addr_type can be one of:
57 | TIPC_ADDR_NAMESEQ, TIPC_ADDR_NAME, and TIPC_ADDR_ID;
58 | and scope can be one of:
59 | TIPC_ZONE_SCOPE, TIPC_CLUSTER_SCOPE, and TIPC_NODE_SCOPE.
60 | The meaning of v1, v2 and v3 depends on the value of addr_type:
61 | if addr_type is TIPC_ADDR_NAME:
62 | v1 is the server type
63 | v2 is the port identifier
64 | v3 is ignored
65 | if addr_type is TIPC_ADDR_NAMESEQ:
66 | v1 is the server type
67 | v2 is the lower port number
68 | v3 is the upper port number
69 | if addr_type is TIPC_ADDR_ID:
70 | v1 is the node
71 | v2 is the ref
72 | v3 is ignored
73 |
74 |
75 | Local naming conventions:
76 |
77 | - names starting with sock_ are socket object methods
78 | - names starting with socket_ are module-level functions
79 | - names starting with PySocket are exported through socketmodule.h
