| 8 | |
Guido van Rossum | c4fcfa3 | 2002-06-07 03:19:37 +0000 | [diff] [blame] | 9 | - Only AF_INET, AF_INET6 and AF_UNIX address families are supported in a |
Christian Heimes | 043d6f6 | 2008-01-07 17:19:16 +0000 | [diff] [blame] | 10 | portable manner, though AF_PACKET, AF_NETLINK and AF_TIPC are supported |
| 11 | under Linux. |
Guido van Rossum | c4fcfa3 | 2002-06-07 03:19:37 +0000 | [diff] [blame] | 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). |

| 51 | - where a hostname is returned, the dd.dd.dd.dd notation is used |
Guido van Rossum | 27e177d | 1995-03-16 15:43:47 +0000 | [diff] [blame] | 52 | - a UNIX domain socket address is a string specifying the pathname |
Jeremy Hylton | 2230865 | 2001-02-02 03:23:09 +0000 | [diff] [blame] | 53 | - an AF_PACKET socket address is a tuple containing a string |
| 54 | specifying the ethernet interface and an integer specifying |
| 55 | the Ethernet protocol number to be received. For example: |
Jeremy Hylton | dbfb662 | 2001-02-02 19:55:17 +0000 | [diff] [blame] | 56 | ("eth0",0x1234). Optional 3rd,4th,5th elements in the tuple |

Christian Heimes | 043d6f6 | 2008-01-07 17:19:16 +0000 | [diff] [blame] | 58 | - an AF_TIPC socket address is expressed as |
| 59 | (addr_type, v1, v2, v3 [, scope]); where addr_type can be one of: |
Antoine Pitrou | f95a1b3 | 2010-05-09 15:52:27 +0000 | [diff] [blame] | 60 | TIPC_ADDR_NAMESEQ, TIPC_ADDR_NAME, and TIPC_ADDR_ID; |
Christian Heimes | 043d6f6 | 2008-01-07 17:19:16 +0000 | [diff] [blame] | 61 | and scope can be one of: |

Christian Heimes | 043d6f6 | 2008-01-07 17:19:16 +0000 | [diff] [blame] | 63 | The meaning of v1, v2 and v3 depends on the value of addr_type: |
Antoine Pitrou | f95a1b3 | 2010-05-09 15:52:27 +0000 | [diff] [blame] | 64 | if addr_type is TIPC_ADDR_NAME: |
| 65 | v1 is the server type |
| 66 | v2 is the port identifier |
| 67 | v3 is ignored |
| 68 | if addr_type is TIPC_ADDR_NAMESEQ: |
| 69 | v1 is the server type |
| 70 | v2 is the lower port number |
| 71 | v3 is the upper port number |
| 72 | if addr_type is TIPC_ADDR_ID: |
| 73 | v1 is the node |
| 74 | v2 is the ref |
| 75 | v3 is ignored |
