hepcat72 has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I have an old module on cpan (my first/only one) that I wrote called IO::Pipe::Producer which basically has 2 functions. It can take a reference to a subroutine or a command for a system call, forks a child which runs it, and returns 2 file handles for the standard out and standard in that can be read from by the parent.

I had forgotten that I'd gone through the "rigor" of creating a package with MakeMaker (I originally used Build), so I was pleasantly surprised that I could install it on my new computer so easily. I started perusing the module and noted a bug report about a hang on Windows when it tried to run the tests. I know virtually zero about Windows and I don't have access to a Windows machine to test it on. Can anyone give me a hint as to why it doesn't work on Windows?

I'd like my current project for which I want to use the module to be able to work on a Windows box if possible.

Thanks,
Rob

    Pipes are files handles and select doesn't work for filehandles on Windows.

    See Win32::SocketPair winopen2() and winopen2_5() for a workaround that redirects the output via sockets in order to alleviate the restriction.

    Whilst not wanting, in any way to tread on toes, I would suggest that, if you intend to develop &/or on Windoze, you get copies of Win32 Perl Scripting &/or Win32 Perl Programming Standard Extensions - they worked wonders for me whilst I was encumbered with M$.

    A user level that continues to overstate my experience :-))
