# setpgrp - perldoc - phpman

    setpgrp PID,PGRP
            Sets the current process group for the specified PID, 0 for the
            current process. Raises an exception when used on a machine that
            doesn't implement POSIX [setpgid(2)](https://www.chedong.com/phpMan.php/man/setpgid/2/markdown) or BSD [setpgrp(2)](https://www.chedong.com/phpMan.php/man/setpgrp/2/markdown). If the
            arguments are omitted, it defaults to "0,0". Note that the BSD
            4.2 version of "setpgrp" does not accept any arguments, so only
            "setpgrp(0,0)" is portable. See also "[POSIX::setsid](https://www.chedong.com/phpMan.php/perldoc/POSIX%3A%3Asetsid/markdown)()".
