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() func-
     tions return zero.

STANDARDS

     The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() func-
     tions conform to IEEE Std 1003.1-2001 (``POSIX.1'').


HISTORY

     The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() func-
     tions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
