opening pipe in windows

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

Hi All,

I am trying to open up a pipe in my perl script (perl in windows, activeperl) but it's giving an error like '-' is not recognized as an internal or external command, operable program or batch file. Opening pipe this way open(F,"-|") for reading. Any idea why it's erroring out? Or is it not supported in Windows? Please help. Thanks

Opening a pipe to yourself is not supported on Windows. See the section on `open` in perlport.	[reply] [d/l]

There is a Win32::Pipe; if that doesn't do what you need then maybe something in Win32 Process will help.	[reply]

This is documented and a workaround can be found in the perlfork man-page. Have a look here: http://docs.activestate.com/activeperl/5.10/lib/pods/perlfork.html#caveats_and_limitations	[reply]
