setpgrp - set the process group of a process


setpgrp PID,PGRP


Sets the current process group for the specified PID, 0 for the current process. Will produce a fatal error if used on a machine that doesn't implement setpgrp. If the arguments are omitted, it defaults to 0,0. Note that the POSIX version of setpgrp does not accept any arguments, so only setpgrp 0,0 is portable.
