Abstract
The present invention is a method and apparatus for providing instrumentation of procedure calls in dynamically linked environments. More specifically, an embodiment of the present invention includes an API that allows a user to define procedures that are called during specific times during the execution of a runtime linker. By defining procedures in accordance with this API, the user can select procedures within a user program for auditing. The API also allows the user to define an entry procedure that will be called immediately before each audited procedure and an exit procedure that will be called immediately after each audited procedure. The runtime linker uses the procedures defined by the user to select procedures within the program for auditing. The runtime linker then arranges for the entry procedure to be called before, and the exit procedure to be called after, each audited procedure.
