# NAME

getpgrp - get process group

# SYNOPSIS

getpgrp PID

# DESCRIPTION

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.
