I'm presently executing the following Linux command in one of my c programs to display processes that are running. Is there anyway I can modify it to show stopped processes and running ones?

char *const parmList[] = {"ps","-o","pid,ppid,time","-g","-r",groupProcessID,NULL};
execvp("/bin/ps", parmList);

jobs -s list stopped process by SIGTSTP,no SIGSTOP. The main difference is that SIGSTOP cannot be ignored.

You can SIGTSTP a process with ^Z or from other shell with kill -TSTP PROC_PID, and then list with jobs.

But what about listing PIDs who had received SIGSTOP? One way to get this is

 ps -e -o stat,command,pid | grep '^S '

I found very useful this two to stop/cont for a while some process (usually the browser):

kill -STOP $(pgrep procName)
kill -CONT $(pgrep procName)

Or with killall

killall -STOP procName
killall -CONT procName
