Python Oserror Winerror 10038

under windows: """ An echo server that uses select to handle multiple clients at a time. Entering any line of input at the terminal will exit the server. """ import select import socket import sys host = '' port = 50000 backlog = 5 size = 1024 server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind((host,port)) server.listen(backlog) input = [server,sys.stdin] running = 1 while running: inputready,outputready,exceptready = select.select(input,[],[]) for s in inputready: if s == server: # handle the server an operation was attempted on something that is not a socket c# socket client, address = server.accept() input.append(client) elif s == sys.stdin: # handle standard input junk = sys.stdin.readline() running = 0 else: # handle all other sockets data = s.recv(size) if data: s.send(data) else: s.close() input.remove(s) server.close() I get the error message (10038, 'An operation was attempted on something that is not a socket'). This probably relates back to the remark in the python documentation that "File objects on Windows are not acceptable, but sockets are. On Windows, the underlying select() function is provided by the WinSock library, and does not handle file descriptors that don’t originate from WinSock.". On internet there are quite some posts on this topic, but they are either too technical for me or simply not clear. So my question is: is there any way the select() statement in python can be used under windows? Please add a little example or modify my code above.

Python Select Windows

helping each other. Join them; it only takes a minute: Sign up python select.select() on Windows up vote 3 down vote favorite 4 I'm testing UDP punching using code from here. It works on Linux however reports error http://stackoverflow.com/questions/10842428/can-select-be-used-with-files-in-python-under-windows on Windows. Here's the code snippet where the error occurs: while True: rfds, _, _ = select([0, sockfd], [], []) # sockfd is a socket if 0 in rfds: data = sys.stdin.readline() if not data: break sockfd.sendto(data, target) elif sockfd in rfds: data, addr = sockfd.recvfrom(1024) sys.stdout.write(data) And error msg: Traceback (most recent call last): File "udp_punch_client.py", line 64, in main() File "udp_punch_client.py", line 50, in main rfds, _, _ = select([0, sockfd], [], []) select.error: http://stackoverflow.com/questions/22251809/python-select-select-on-windows (10038, '') I know this error has some thing to do with the select implementation on Windows, and everyone quote this: Note File objects on Windows are not acceptable, but sockets are. On Windows, the underlying select() function is provided by the WinSock library, and does not handle file descriptors that don’t originate from WinSock. So I got two questions: What does 0 in [0, sockfd] mean? Is this some sort often-used technique? If select only works with socket on Windows, How to make the code Windows compatible?

What you need is a way to read stdin without blocking. You may use: An extra thread for stdin. That should work fine and be the easiest way to do the job. Python threads support i

So I was wondering how I can change the code above to run on windows xp. Any help would greatly appreciated.
