setpgrp - set process group
SYNOPSIS
setpgrp(pid, pgrp)
int pid, pgrp;
DESCRIPTION
Setpgrp
sets the process group of the specified process
pid

must have the same effective user-id as the invoker or be a descendant
of the invoking process.

returns when the operation was successful. If
the request failed, -1 is returned and the global
variable

indicates the reason.

will fail and the process group will not be altered if
one of the following occur:

-
The requested process does not exist.
- [EPERM]
-
The effective user ID of the requested process is different
from that of the caller and the process is not a descendent
