POSIX_SPAWNATTR_GETSIGDEFAULT(3C) Standard C Library Functions

NAME

posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault - get and
set spawn-sigdefault attribute of spawn attributes object

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 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.

RETURN VALUES

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.

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.
