POSIX_SPAWNATTR_GETSIGMASK(3) FreeBSD Library Functions Manual
NAME
posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get and set the
spawn-sigmask attribute of a spawn attributes object
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#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);
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
The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask()
functions return zero.
