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) or BSD setpgrp(2). 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()
.
