POSIX_SPAWNATTR_GETSIGMASK(3C) Standard C Library Functions
NAME
posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get and set
spawn-sigmask attribute of spawn attributes object
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 obtains the value of the
spawn-sigmask attribute from the attributes object referenced by
attr.
The
posix_spawnattr_setsigmask() function sets 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 VALUES
Upon successful completion,
posix_spawnattr_getsigmask() returns 0
and stores the value of the
spawn-sigmask attribute of
attr into the
object referenced by the
sigmask parameter. Otherwise, an error
number is returned to indicate the error.
Upon successful completion,
posix_spawnattr_setsigmask() 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_setsigmask() function may fail if:
EINVAL The value of the attribute being set is not valid.
