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().

       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.
