Guido van Rossum | 6574b3e | 1991-06-25 21:36:08 +0000 | [diff] [blame] | 5 | This module provides an interface to Berkeley socket IPC. |

| 7 | Limitations: |
| 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 |
Jeremy Hylton | 2230865 | 2001-02-02 03:23:09 +0000 | [diff] [blame] | 10 | portable manner, though AF_PACKET is supported under Linux. |
Guido van Rossum | c4fcfa3 | 2002-06-07 03:19:37 +0000 | [diff] [blame] | 11 | - No read/write operations (use sendall/recv or makefile instead). |
| 12 | - Additional restrictions apply on some non-Unix platforms (compensated |
| 13 | for by socket.py). |
