Abstract

A hooking system for hooking predetermined references to predetermined dynamically loaded library (DLL) functions includes a DLL version identifier provided by a hook entry code to an enhanced hook. The hook entry code is dynamically generated during runtime of an affected software application. The version identifier enables unambiguous communication of a single enhanced hook with functions of multiple versions of identically named DLLs loaded into the same isolated process memory area.

First claim

Accordingly, the scope of the invention described in the Figures and Specification above is set forth by the following claims and their legal equivalent:

1. A method, comprising operations of:
identifying, during execution of a software application, a first reference to a function in the software application, wherein the first reference corresponds to a first version of a dynamically loaded library (DLL) with a first version of the function;
dynamically generating a first hook-e…
