getpgrp
getpgrp pid
Returns the current process group for the specified process
ID (
pid
).
Use a
pid
of
0
for the current process.
Invoking
getpgrp
will produce a fatal error if used on a machine
that doesn't implement the
getpgrp
system call.
If
pid
is omitted, the
function returns the process group of the current process (the same as
using a
pid
of
0
). On systems implementing this operator with the
POSIX
getpgrp(2)
system call,
pid
must be omitted or, if
supplied, must be
0
.
