Why not use pgrep?

pgrep -g0

gives you the list of PID's of the processes in the group of the process which is current. (See man pgrep)

Note that the command outputs nothing, if job control (set -m) is active in shell, because current process has a new process group then.

Use ps to get the pgid of a process:

ps -o pgid $$
