Fellow Monks,
In one of my scripts I start up several child processes as follows foreach $item ( @array ) {
if( $pid = fork ) {
print "Forking off to $pid\n";
} elsif( defined $pid ) {
&proprietary_function( $item );
print "Done with function\n";
exit;
} else {
die "Can't fork: $!";
}
}
My question is this:
If I were to build up a list of PID's, how could I wait for them all to exit, and if they don't exit after a certain amount of time, kill them?
I've looked at perlipc and wait but I'm getting kind of confused about reaping and when to handle it.
Could I use something like sub REAPER {
my $waitedpid = wait;
$SIG{CHLD} = \&REAPER;
}
And then change if( $pid = fork ) {
print "Forking off to $pid\n";
To if( $pid = fork ) {
$SIG{CHLD} = \&REAPER;
print "Forking off to $pid\n";
?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
