NAME
posix_spawnattr_getsigmask,
posix_spawnattr_setsigmask —
get and set the spawn-sigmask attribute
of a spawn attributes object
LIBRARY
library “libc”
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_getsigmask(const
posix_spawnattr_t *restrict attr,
sigset_t *restrict
sigmask);
int
posix_spawnattr_setsigmask(posix_spawnattr_t
*attr, const sigset_t
*restrict sigmask);
DESCRIPTION
Theposix_spawnattr_getsigmask()
function obtains the value of the spawn-sigmask attribute from the attributes
object referenced by attr.
The
posix_spawnattr_setsigmask()
function sets the spawn-sigmask attribute in an initialized attributes
object referenced by attr.
The spawn-sigmask attribute represents the signal mask in effect
in the new process image of a spawn operation (if
POSIX_SPAWN_SETSIGMASK is set in the spawn-flags
attribute). The default value of this attribute is unspecified.
RETURN VALUES
The posix_spawnattr_getsigmask() and
posix_spawnattr_setsigmask() functions return
zero.
