posix_spawnattr_getsigmask(3C) Standard C Library Functions posix_spawnattr_getsigmask(3C)
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.
