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.
