getpgrp - get process group
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.
