NAME
posix_spawnattr_getsigdefault,

attribute of a spawn attributes object
LIBRARY
library “libc”
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_getsigdefault(const
posix_spawnattr_t *restrict attr,
sigset_t *restrict
sigdefault);
int
posix_spawnattr_setsigdefault(posix_spawnattr_t
*attr, const sigset_t
*restrict sigdefault);
DESCRIPTION
Theposix_spawnattr_getsigdefault()
function obtains the value of the spawn-sigdefault attribute from the
attributes object referenced by attr.
The
posix_spawnattr_setsigdefault()
function sets the spawn-sigdefault attribute in an initialized attributes
object referenced by attr.
The spawn-sigdefault attribute represents the set of signals to be
forced to default signal handling in the new process image (if
POSIX_SPAWN_SETSIGDEF is set in the spawn-flags
attribute) by a spawn operation. The default value of this attribute is an
empty signal set.
RETURN VALUES
The posix_spawnattr_getsigdefault() and
posix_spawnattr_setsigdefault() functions return
zero.
