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