Abstract
A method of operating a digital computer to provide instrumentation data for a shared library running in an environment in which programs are loaded and unloaded by a loader. The environment supports the operation of at least one program in addition to the shared library, the program utilizing at least one function provided by the shared library. The operating environment includes storage for a predetermined environment variable that may be read by any program running in the environment. The method includes the steps of causing the loader to examine the environment to determine if the predetermined environment variable has been set; and storing profile based optimization data stored in the shared library code in a location specified by the predetermined environmental variable if the predetermined environmental variable was present in response to a command being sent to the loader. The profile based optimization data is normally stored when the shared library is unloaded from the operating environment by the loader.
