I'm not even sure the title is the appropriate terminology. What I am
trying to do is fork a process that receives data from the parent, but,
once the data is received, the parent can go on and do whatever it wants
(and likewise the child). How do I arrange for the child process to be
detached once the data is sent to it?
Put another way, I do NOT want the parent to block waiting for the child
to exit.
Here is (in summary) the code I am using (which was adapted from section
16.10 of the Perl Cookbook):
if($pid = open(CHILD, "|-"))
{
CHILD->autoflush(1);
$sprm = $type . "(". "S" . $arg1 . $arg2 . ")";
print CHILD "\"$sprm\n";
Lots of other output logic here....
close CHILD;
next;
}
else
{
die "cannot fork: $!" unless defined $pid;
exec "xgraph $plotargs";
exit;
}
Basically, I want xgraph to have a life of its own after the data is
received and plotted.
Any clues?
Thanks in advance,
