POSIX_SPAWNATTR_GETSIGMASK(3)				   BSD Library Functions Manual 			     POSIX_SPAWNATTR_GETSIGMASK(3)

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.

STANDARDS
The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions first appeared in FreeBSD 8.0.
