posix_spawnattr_getsigmask3
Get and set the spawn-sigmask attribute of a spawn attributes object
Usage
#include <spawn.h>
int
posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr, sigset_t *restrict sigmask);
int
posix_spawnattr_setsigmask(posix_spawnattr_t *attr, const sigset_t *restrict sigmask);
Library
Standard C Library (libc, -lc)
Overview
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
The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions return zero.
