SYNOPSIS

9       #include <unistd.h>
10
11       pid_t setpgrp(void);

DESCRIPTION

15       If  the calling process is not already a session leader, setpgrp() sets
16       the process group ID of the calling process to the process  ID  of  the
17       calling  process. If setpgrp() creates a new session, then the new ses‐
18       sion has no controlling terminal.
19
20       The setpgrp() function has no effect when the calling process is a ses‐
21       sion leader.
22

RETURN VALUE

24       Upon completion, setpgrp() shall return the process group ID.
