POSIX_SPAWNATTR_GETSIGMASK(P) POSIX_SPAWNATTR_GETSIGMASK(P)
NAME
posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get and set the spawn-sig-
mask attribute of a spawn attributes object (ADVANCED REALTIME)
SYNOPSIS
#include <signal.h>
#include <spawn.h>
int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
sigset_t *restrict sigmask);
int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr,
const sigset_t *restrict sigmask);
DESCRIPTION
The posix_spawnattr_getsigmask() function shall obtain the value of the spawn-sig-
mask attribute from the attributes object referenced by attr.
The posix_spawnattr_setsigmask() function shall set the spawn-sigmask attribute in
an initialized attributes object referenced by attr.
The spawn-sigmask attribute represents the signal mask in effect in the new process
image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is set in the spawn-flags
attribute). The default value of this attribute is unspecified.
RETURN VALUE
Upon successful completion, posix_spawnattr_getsigmask() shall return zero and
store the value of the spawn-sigmask attribute of attr into the object referenced
by the sigmask parameter; otherwise, an error number shall be returned to indicate
the error.
Upon successful completion, posix_spawnattr_setsigmask() shall return zero; other-
wise, 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_setsigmask() 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 imple-
mentations.
RATIONALE
None.
FUTURE DIRECTIONS
None.
