select.select() on windows

[jas]

I am currently using subprocess to execute a command. Then I read from
it's stdout...however, this is hanging on a read..waiting for more
bytes. So what I would like is to timeout...and select.selec() seems
to be what I need. Except I don't have a socket, i have stdout.

Any suggestions on how to do a timeout like select.select with stdout?

Thanks

you have to use non-block readining.

http://docs.python.org/lib/module-select.html:
A time-out value of zero specifies a poll and never blocks.

I am not too familiar with any asynchronous I/O facilities in Python
beyond select, so in your situation I would use the threading module,
with the blocking read in one thread and your time-out in the main
thread. You could perhaps use an Event object here, which has the
time-out functionality for you.

Did you miss the subject line... "... on windows"? select() only
works with sockets on windows, not on regular file streams.
