7       spawn-pgroup attribute of spawn attributes object

SYNOPSIS

10       #include <spawn.h>
11
12       int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
13            pid_t *restrict pgroup);

16       int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);

DESCRIPTION

20       The posix_spawnattr_getpgroup()  function  obtains  the  value  of  the
21       spawn-pgroup attribute from the attributes object referenced by attr.
22
23
24       The   posix_spawnattr_setpgroup()   function   sets   the  spawn-pgroup
25       attribute in an initialized attributes object referenced by attr.
26
27
28       The spawn-pgroup attribute represents the process group to be joined by
29       the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is
30       set in the spawn-flags attribute). The default value of this  attribute
31       is zero.
32

RETURN VALUES

34       Upon  successful  completion, posix_spawnattr_getpgroup() returns 0 and
35       stores the value of the spawn-pgroup attribute of attr into the  object
36       referenced  by  the  pgroup  parameter.  Otherwise,  an error number is
37       returned to indicate the error.
