NAME

posix_spawnattr_getsigmask posix_spawnattr_setsigmask — get and set the spawn-sigmask attribute of a spawn attributes object (ADVANCED REALTIME)

SYNOPSIS

[SPN]
#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-sigmask 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; otherwise, an error number shall be returned to indicate the error.
