Windows NT select.select( )

[David Cattarin]

I recently had to write an EventLoop class to replace the
asyncore.poll( ) function since I need to support timers
as well as sockets in my application. There was an oddity
under Windows NT that when no sockets were registered to
the socket_map select failed. This code worked fine under
UNIX. For example, select( [ ], [ ], [ ], 5 ) will
raise a "file does not exist" error under Windows NT.

Has anyone else noticed this? I've worked around it by
creating an unconnected socket and placing it in the
exception list; ie. select( [ ], [ ], [ s ], 5 ). This
allows the code to work under Windows and UNIX.

I am using Python 1.5.2, the precompiled version. I am
pretty sure it is just a Windows NT oddity and not a
Python problem, but I was curious if anyone knew more.
Or even a better way to fix this.

Thanks for your help.
