public class SharedUnixLibrary

extends SWIHandler

Java implementation of Peter Naulls' module used by UnixLib programs. From: http://www.drobe.co.uk/riscos/artifact1253.html What is SharedUnixLibary? I want to say very little about this, since it's been a huge cause of confusion for no good reason. Its singular, and only purpose, is to catch a callback that RISC OS makes when an application quits. RISC OS helpfully insists on calling this (for a variety of reasons) when the listening application might be paged out, thereby jumping to random code and quickly causing your computer to freeze or crash some unrelated program. This code is therefore in a module and only passes the message onto Unixlib when it is safe to do so. The issue has been fixed in Select/Adjust, but Unixlib has not been modified to avoid this on machines running those versions of RISC OS. NB: This is in no way similar in operation to SharedCLibrary.
