I created child process using fork and I want the child to halt execution and the parent to continue. Is there any handler avaiable in perl 5.6 like SIGSTOP? I have searched everywhere and not been able to find the information.
Below is the code that I tried but ctrl C will stop execution for both the processes
#!/usr/bin/perl
use strict;
use warnings;
$|=1;
my $pid = fork;
die "Cannot fork: $!" unless defined $pid;
unless($pid) {
print "Child start\n";
my $end;
local $SIG{INT} = sub { $end = 1 };
while(1){
sleep(1);
until($end)
{
print ".";
sleep(1);
}
}
exit 0;
}
print "Parent start\n";
for(my $i = 0; ;$i++){
sleep 1;
print "*";
if($i == 10){
kill INT => $pid;
}
}
Please don't mind if I am wrong in any way, I am quite new to system level programming :-(

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).
