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

|
|
|
|
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.
