NAME
posix_spawnattr_getpgroup,
posix_spawnattr_setpgroup —
get and
set the spawn-pgroup attribute of a spawn attributes object
LIBRARY
Standard C Library (libc, -lc)
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
The
posix_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.
