Subject: docs of using system()

The docs of IPC::Run3 could make it clear somewhere at the start of the description that it's the system() function which is used to run the program. system differs subtly from qx or fork+exec in respect of SIGINT ignoring. There's no doubt a place for both, but run3 could make it clear which it does.

I'm open to suggestions :) Cheers, Roderich

Maybe something like C<run3> uses the C<system> function to run a subprocess or shell command, with stdin, stdout, and/or stderr conveniently redirected to or from files, Perl data structures, or subroutines. It aims to satisfy 99% of the need for "system", "qx", and "open3" with a simple, extremely Perlish API. The way SIGINT is ignored in system(), and thus run3(), over qx probably should be noted or cross referenced somewhere early on, but I'm not sure how to word that without labouring it. Of course having sigint only kill the child might be a feature anyway -- you can look at its exit code to see how it died. Most of the time though I tend to think I want the parent and child both to die under a ^C ...

Applied :) and added some wording about "same restrictions as system()". Cheers, Roderich

Probably this should've been closed when applied. Closing now. -- rjbs
