POSIX_SPAWNATTR_GETSIGIGNORE_NP(3C)POSIX_SPAWNATTR_GETSIGIGNORE_NP(3C)NAME
posix_spawnattr_getsigignore_np, posix_spawnattr_setsigignore_np - get
and set spawn-sigignore attribute of spawn attributes object
SYNOPSIS
#include <signal.h>
#include <spawn.h>
int posix_spawnattr_getsigignore_np(
const posix_spawnattr_t *restrict attr,
sigset_t *restrict sigignore);
int posix_spawnattr_setsigignore_np(
posix_spawnattr_t *restrict attr,
const sigset_t *restrict sigignore);
DESCRIPTION
The posix_spawnattr_getsigignore_np() function obtains the value of the
spawn-sigignore attribute from the attributes object referenced by
attr.
The posix_spawnattr_setsigignore_np() function sets the spawn-sigignore
attribute in an initialized attributes object referenced by attr.
The spawn-sigignore attribute represents the set of signals to be
forced to be ignored in the new process image (if POSIX_SPAWN_SET‐
SIGIGN_NP is set in the spawn-flags attribute) by a spawn operation.
The default value of this attribute is an empty signal set.
RETURN VALUES
Upon successful completion, posix_spawnattr_getsigignore_np() returns 0
and stores the value of the spawn-sigignore attribute of attr into the
object referenced by the sigignore parameter. Otherwise, an error
value is returned to indicate the error.
Upon successful completion, posix_spawnattr_setsigignore_np() returns
0. Otherwise, an error value is returned to indicate the error.
ERRORS
These functions may fail if:
EINVAL
The value specified by attr is invalid.
The posix_spawnattr_setsigignore_np() function may fail if:
EINVAL
The value of the attribute being set is not valid.
