Имя (Name)
posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault —
get and set the spawn-sigdefault attribute of a spawn attributes
object (ADVANCED REALTIME)
Синопсис (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);
Описание (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.
Возвращаемое значение (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.
