Parent Process id.

[rajendra]

Hello All,

If I open an application from a command prompt, then command prompt becomes
the parent process of the application.

Is there a perl command to get the parent process id for an application?.

I assume by 'command' you mean function. It may help you to know that
ALL built-in Perl functions are listed in the man page:
perldoc perlfunc

Within that documentation they are sorted by category type. If you
scroll down, you will see this:

Functions for processes and process groups
"alarm", "exec", "fork", "getpgrp", "getppid",
"getpriority", "kill", "pipe", "qx/STRING/", "setpgrp",
"setpriority", "sleep", "system", "times", "wait",
"waitpid"

Once you find the function that looks likely, 'getppid', you can then
do:
perldoc -f getppid

to read all about how to use it.

Hope this helps,

Is getppid () is only for UNIX platform?...
