nonblocking char reads from OUTPUT stream from open3by Eradicatore (Monk)
|on Dec 14, 2002 at 20:48 UTC||Need Help??|
Eradicatore has asked for the wisdom of the Perl Monks concerning the following question:
I'm tryinig to use Open3() to open up a seperate process on windows, and then read characters one at a time with ReadKey (or getc) from the OUTPUT stream from the open3() call. The problem I have is that sometimes the seperate process will just sit there waiting for the user to enter "y" or "n". At this point, my loop that is getting chars one at a time hangs, and it doesn't seem to even get any of the chars from that last line where the seperate program was waiting for input. I've been hunting around but I don't seem to be able to tie this all together myself.
I've tried setting ReadMode of the OUTPUT stream to 5 or 4, but in windows using activestate perl 5.6.0 it sends back this error:
GetConsoleMode failed, LastError=|6| at D:/Perl/site/lib/Term/ReadKey.pm line 245.
If anyone has any suggestions, I would really appreciate it. Thanks!
