/*

The idea of this module is to implement reasonable minimum of
|
|
|
|
socket-related functions to write typical clients and servers.
|
2014-10-09 18:43:10 +01:00
|
|
|
The module named "usocket" on purpose, to allow to make
|
2014-05-30 23:48:26 +01:00
|
|
|
Python-level module more (or fully) compatible with CPython
|
|
|
|
"socket", e.g.:
|
|
|
|
---- socket.py ----
|
2014-10-09 18:43:10 +01:00
|
|
|
from usocket import *
|
2014-05-30 23:48:26 +01:00
|
|
|
from socket_more_funcs import *
|
|
|
|
from socket_more_funcs2 import *
|
|
|
|
-------------------
|
|
|
|
I.e. this module should stay lean, and more functions (if needed)
|
|
|
|
should be add to seperate modules (C or Python level).
