of a spawn attributes object
LIBRARY

SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_getpgroup(const
posix_spawnattr_t *restrict attr,
pid_t *restrict
pgroup);
int
posix_spawnattr_setpgroup(posix_spawnattr_t
*attr, pid_t
pgroup);
DESCRIPTION
Theposix_spawnattr_getpgroup()
function obtains the value of the spawn-pgroup attribute from the attributes
object referenced by attr.
The
posix_spawnattr_setpgroup()
function sets the spawn-pgroup attribute in an initialized attributes object
referenced by attr.
The spawn-pgroup attribute represents the process group to be
joined by the new process image in a spawn operation (if
POSIX_SPAWN_SETPGROUP is set in the spawn-flags
attribute). The default value of this attribute is zero.
RETURN VALUES
The posix_spawnattr_getpgroup() and
posix_spawnattr_setpgroup() functions return
zero.
