+.Fd #include <signal.h>
+.Ft int
+.Fn sigwait "const sigset_t *set" "int *sig"
+.Sh DESCRIPTION
+The
+.Fn sigwait
+function selects a set of signals, specified by
+.Fa set .
+If none of the selected signals are pending,
+.Fn sigwait
+waits until one or more of the selected signals has been generated.
+Then
+.Fn sigwait
+atomically clears one of the selected signals from the set of pending signals
+for the process and sets the location pointed to by
+.Fa sig
+to the signal number that was cleared.
+.Pp
+The signals specified by
+.Fa set
+should be blocked at the time of the call to
+.Fn sigwait .
+.Sh RETURN VALUES
+If successful,
+.Fn sigwait
+returns 0 and sets the location pointed to by
+.Fa sig
+to the cleared signal number.
+Otherwise, an error number is returned.
+.Sh ERRORS
+.Fn sigwait
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+.Fa set
+specifies one or more invalid signal numbers.
