NAME
posix_spawnattr_getsigdefault,
posix_spawnattr_setsigdefault
--- get and set the spawn-sigdefault attribute of a spawn attributes object
(ADVANCED REALTIME)
SYNOPSIS
#include <signal.h>
#include <spawn.h>
int posix_spawnattr_getsigdefault(const posix_spawnattr_t
*restrict attr, sigset_t *restrict sigdefault);
int posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict attr,
const sigset_t *restrict sigdefault);
DESCRIPTION
The
posix_spawnattr_getsigdefault()
function shall obtain the value of the
spawn-sigdefault
attribute from the attributes object referenced by
attr.
The
posix_spawnattr_setsigdefault()
function shall set 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
shall be an empty signal set.
RETURN VALUE
Upon successful completion,
posix_spawnattr_getsigdefault()
shall return zero and store the value of the
spawn-sigdefault
attribute of
attr
into the object referenced by the
sigdefault
parameter; otherwise, an error number shall be returned to indicate the
error.
Upon successful completion,
posix_spawnattr_setsigdefault()
shall return zero; otherwise, an error number shall be returned to
indicate the error.
ERRORS
These functions may fail if:
- EINVAL
-
The value specified by
attr
is invalid.
The
posix_spawnattr_setsigdefault()
function may fail if:
- EINVAL
-
The value of the attribute being set is not valid.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
These functions are part of the Spawn option and need not be
provided on all implementations.
RATIONALE
None.
FUTURE DIRECTIONS
None.
