PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       setpgrp - set the process group ID
SYNOPSIS
       #include <unistd.h>
       pid_t setpgrp(void);

DESCRIPTION
       If the calling process is not already a session leader, setpgrp()  sets
       the  process  group  ID of the calling process to the process ID of the
       calling process. If setpgrp() creates a new session, then the new  ses-
       sion has no controlling terminal.
       The setpgrp() function has no effect when the calling process is a ses-
       sion leader.
RETURN VALUE
       Upon completion, setpgrp() shall return the process group ID.
