50.Sh DESCRIPTION
51The
52.Fn posix_spawnattr_getsigmask
53function obtains the value of the spawn-sigmask attribute from the
54attributes object referenced by
55.Fa attr .
56.Pp
57The

59function sets the spawn-sigmask attribute in an initialized attributes
60object referenced by
61.Fa attr .
62.Pp
63The spawn-sigmask attribute represents the signal mask in effect in the
64new process image of a spawn operation (if
