NAME
       setsid, getpgrp - create process group, get process group id

SYNOPSIS
       #include <sys/types.h>
       #include <unistd.h>

       pid_t setsid(void)
       pid_t getpgrp(void)

DESCRIPTION
       Setsid()	 creates a new session if the calling process is not already a
       session leader.	The calling process becomes the session	 leader	 of  a
       new  process  group  and the process group ID of this new process group
       will be equal to the process ID of the new session leader.  The process
       group ID is inherited on a fork(2).

       Getpgrp() returns the process group ID of the calling process.

SEE ALSO
       kill(2), termios(3), tty(4).

DIAGNOSTICS
       Setsid()	 returns the new process group ID on success, or -1 with errno
       set to EPERM if the process is already a session leader.
