posix_spawnattr_getsigdefault posix_spawnattr_setsigdefaultget and set the spawn-sigdefault attribute of a spawn attributes object (ADVANCED REALTIME)


#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);

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 attribute) by a spawn operation. The default value of this attribute shall be an empty signal set.

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 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.

These functions may fail if:

The value specified by attr is invalid.

The posix_spawnattr_setsigdefault () function may fail if:

The value of the attribute being set is not valid.

None.

These functions are part of the Spawn option and need not be provided on all implementations.

None.

None.
