NAME

posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault —

get and set the spawn-sigdefault attribute of a spawn attributes object

LIBRARY

Standard C Library (libc, -lc)

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

The posix_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.

STANDARDS

The posix_spawnattr_getsigdefault() and posix_spawnattr_setsigdefault() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

HISTORY

The posix_spawnattr_getsigdefault() and posix_spawnattr_setsigdefault() functions first appeared in FreeBSD 8.0.
