How do I make a system() exit on control-C?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

You can't. You need to imitate the system() call (see the perlipc manpage for sample code) and then have a signal handler for the INT signal that passes the signal on to the subprocess. Or you can check for it:

    $rc = system($cmd);
    if ($rc & 127) { die "signal death" }

[stevieb]: corelist List::Util::XS says "List::Util::XS was first released with perl v5.10.1"
[stevieb]: so yes, since v5.10.1 :)
[MidLifeXis]: According to [metaperl:// corelist], Perl 5.10.1
Lady_Aleena blurbles. One of her favorite modiles is now in "maintenance mode" in favor of a new fangled module.
[MidLifeXis]: D'oh. Slow out of the gate.
[marioroy]: Thanks stevieb, MidLifeXis.
[MidLifeXis]: corelist Typo. Wow. Time to go, fingers are malfunctioning.
[marioroy]: Thanks MidLifeXis. Leaned another thing about Perl. Wow.
