POSIX_SPAWNATTR_GETSIGDEFAUPOSIX Programmer's POSIX_SPAWNATTR_GETSIGDEFAULT(P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
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-sigde‐
fault 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.
