getpgrp PID
Returns the current process group for the specified
PID. Use
a
PID of 0 to get the current process group for the
current process. Will raise an exception if used on a machine that
doesn't implement getpgrp(2). If
PID is omitted, returns process
group of current process. Note that the
POSIX version of getpgrp
does not accept a
PID argument, so only PID==0 is truly portable.
