50This interface is made obsolete by:
51.Ef
52.Xr sigprocmask 2 .
53.Pp
54.Fn Sigsetmask
55sets the current signal mask. Signals
56are blocked from delivery if the
57corresponding bit in
58.Fa mask
59is a 1; the macro

61is provided to construct the mask for a given
62.Fa signum .
63.Pp
64The system
