socket.inet_ntop, and pton question

Hi

Are these functions (inet_ntop(), inet_pton()) from the socket library
supported on Windows.

If not is there an equivalent for them using Windows

Ive seen mention of people creating their own in order to use them

Appreciate the help

Why didn't you just try:

[E:\Projects]python
Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.inet_aton("127.0.0.1")
'\x7f\x00\x00\x01'
>>> socket.inet_ntoa(_)
'127.0.0.1'
>>>


This is on windows xp.

But these are not the requested functions, inet_ntop() and inet_pton():

py> socket.inet_ntop
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'module' object has no attribute 'inet_ntop'

Oops, my bad. Should have had more coffee before replying I guess.

You can use the below code:
def inet_ntop(address_family, packed_ip):
if address_family != AF_INET:
raise socket.error, (97, 'Address family not supported by protocol')
lIP = []
for ch in packed_ip:
lIP.append(str(ord(ch)))
strIP = string.join(lIP,'.')
return strIP

def inet_pton(address_family, ip_string):
if address_family != AF_INET:
raise socket.error, (97, 'Address family not supported by protocol')
lIP = ip_string.split('.')
strHexIP = ""
for i in lIP:
if i == '':
continue
strHex = "%x" % int(i)
strHex = strHex.zfill(2)
strHexIP += "\\x"+strHex
return strHexIP
