posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault - get and set spawn-sigdefault attribute of spawn attributes object
#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 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.
Upon successful completion, posix_spawnattr_getsigdefault() returns 0 and stores the value of the spawn-sigdefault attribute of attr into the object referenced by the sigdefault parameter. Otherwise, an error number is returned to indicate the error.
Upon successful completion, posix_spawnattr_setsigdefault() returns 0. Otherwise, an error number is returned to indicate the error.
These functions may fail if:
EINVAL
The posix_spawnattr_setsigdefault() function may fail if:
EINVAL
