Subject: Excessive wait time after fork
Hi,
I noticed that after fork, the wait time is excessive (my other
test waited for hours). Is this a known
id show that less than half of the total memory is used. So I don't

Hi,

This happens with ForkManager module also.
Any pointers on what's going on is appreciated!

spawn() funtion, and enabling autoflush. Doesn't do the trick either,
and I don't know how to reset STDOUT to the default afterwards.

There are two questions pertaining to this

In other words, is it possible to list out the files in perl?

Yes,like all other program languages,you can use "sleep" for the delay.
see "perldoc -f sleep".
if you want to get a sleep of milliseconds,you can use the four arguments
version "select",like:
# sleep of 250 milli
You can use "sleep".

Joshua,
Thanks for the advice. While this may be true, the complexity of
setting up such a solution is far beyond my abilities and time right
now.
Also, this is more of a generic IPC type question as I could apply a
wait/pid solution in a number of more localised scenarios.
Thanks!

Hi,
At reaching a certain point in my perl program, I need to run a process
( say XYZ ) using SYSTEM command. The result file that this process
would produce will be result.. I will have to wait until
this result file is produced & then proceed extracting certain things
from this file.

Dear all :
I see these lines in a perl program :
$pif = fork;
if($pid == 0) {
exec("hpxy -s xxx.abc");
}else{
$pid1=wait;
}
I could understand that the fork is needed here to get into the child
process "hpxy" !!
What is the need for the "wait" here ??

The beginner shines in me...
For reaping children,
I was thinking of send a signal to the entire group.
The gist is:
I want to attach a child to a FIFO, then have the parent start other
processes that read from the FIFO. The readers must be tricked into
thinking they are reading from files.
I'd like to fork my program without waiting for the child to exit.
My child will be a sub with an infinite loop, so I'd like the parent to
continue on it's merry way.
Solutions?

AFAIR, system() won't return unless it is finished or the process has been
killed. So you wont need an additional sleep() command.
