SETSID 2
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.
