Name
setpgrp
Synopsis
setpgrp pid, pgrp
Sets the current process group
pgrp for the specified
pid (use a
pidof 0 for the current process). Invoking
setpgrp will produce a fatal
error if used on a machine that doesn’t implement setpgrp(2). Some systems will ignore the
arguments you provide and always do setpgrp(0, $$). Fortunately, those are
the arguments you usually provide. (For better portability, use
the setpgid( ) function in the
POSIX module, or if you’re really just trying to daemonize your
script, consider the POSIX::setsid(
) function as well.)
