From f85c1874594a92caed396cf91603072d2951b21b Mon Sep 17 00:00:00 2001
From: Kevin Day <thekevinday@gmail.com>
Date: Tue, 19 Jul 2022 22:19:51 -0500
Subject: [PATCH] Feature: Add missing signal functions f_signal_action(),
 f_signal_pause(), and f_signal_suspend().

The f_signal_pause() just calls pause() and returns F_none.
The return value of pause() is meaningless if I am understanding the man pages correctly.
It should always return -1 and then sets errno despite this not being an actual error.
