    *restrict sigmask);
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.
posix_spawnattr_getsigmask() and
  posix_spawnattr_setsigmask() functions return zero.
posix_spawnattr_getsigmask() and
  posix_spawnattr_setsigmask() functions conform to
  IEEE Std 1003.1-2001 (“POSIX.1”).
posix_spawnattr_getsigmask() and
  posix_spawnattr_setsigmask() functions first appeared
  in FreeBSD 8.0 and imported for
  NetBSD 6.0.
