Capturing PIDs of same process at different instances
Hi,
I'm gonna launch a process from my 'C' code. I'm gonna launch it a few times. I would like to capture the PID of that process each time I launch. I have to copy the each PIDs into a 'C' variable and I have to kill all of them when I exit from the 'C' code.
My requirement is
int pid_var1;
int pid_var2;
int pid_var3;
system(launch_pro); //Instance 1
pid_var1 = PID (launch_pro); // How do I do this???
I have to repeat this for all the instances.
Thanks,

ivman-launch
IVMAN-LAUNCH(8) System Manager's Manual IVMAN-LAUNCH(8)
NAME
ivman-launch - launch script for Ivman
SYNOPSIS
ivman-launch [ --exit-with-session <cmd> ] [ OPTIONS ] [ COMMAND [ ARGS... ]]
DESCRIPTION
ivman-launch is a simple script used to launch Ivman. Its sole purpose is to ensure Ivman is closed at the end of a user's login session.
You can use it if your session manager does not properly close Ivman when you log out.
ivman-launch supports the same command-line options as Ivman, and one additional option: --exit-with-session. Thus, there is no point
using ivman-launch if you do not need to use this option.
If you supply a COMMAND (with optional ARGS), the the specified command will be run after ivman is started, and ivman will be killed after
that command exits.
OPTIONS
--exit-with-session <cmd>
ivman-launch will block until the command 'cmd' terminates, at which point it will kill Ivman and exit itself. If the command 'cmd'
is not running when ivman-launch is started, Ivman will exit immediately. Note that this option implies Ivman will be called with
the '--nofork' option. option.
--debug --nofork --system
These flags be passed to the launched ivman command.
EXAMPLES
ivman-launch --exit-with-session xinit &
The ivman process will be started, then the xinit process is watched. When the xinit process exits, ivman is killed. Placing this
command in an ~/.xinitrc file would cause Ivman to launch in the background when your session begins, and exit when your session
ends:
ivman-launch /usr/bin/x-window-manager
The ivman process is launched, then /usr/bin/x-window-manager is run, when x-window-manager exits, ivman is killed. This is an
example of how ivman might be launched from Xsession in order to chain several programs together in one session.
