reaper - support for reaping child processes via $SIG{CHLD}
use reaper qw( reaper reapPid pidStatus );
my $pid = fork;
if ( $pid == 0 ) { # child
exec $some_command;
}
reapPid ( $pid );
...
if ( defined(my $exit = pidStatus($pid)) ) {
# child exited, check the code...
}
reaper is just a backwards-compatibility wrapper for Reaper -- turns out that
only 'pragmas' are supposed to be named in lower case, so I renamed reaper to
Reaper. But existing code contains 'use reaper', so this allows such code to
work without changes.
