Track: Programming

Speaker
Robert Gezelter, Principal, Robert Gezelter Software Consultant


Description
Asynchronous System Traps (ASTs) are a core concept of OpenVMS. ASTs are available for timers, IO completion, lock management events, and other system services. However, many are not aware of the how to safely use AST-based mechanisms. There are also a surprising number of inaccurate beliefs concerning ASTs. This session will introduce the concepts needed to safely use ASTs in user code. It will discuss how to implement ASTs for timers, IO operations, and other purposes. Familiarity with a standard OpenVMS high-level language will be presumed.
