Dynamic software wrapper

A system for intercepting a non-exported function in an application software module on a distributed component object model server comprising:

• a distributed component object model server comprising a processor and an addressable memory unit for storing the non-exported function, and a registry for storing an identifier identifying the non-exported function;
• an exported function stored in the memory unit, the exported function adopted to retrieve the identifier by scanning the registry;
• a table for storing a memory address where the non-exported function is stored in the memory unit, the identifier further for identifying the memory address in the table;
• and
• an interceptor software program for intercepting the exported function and for executing the exported function to retrieve the identifier from the registry, the interceptor software program further for locating the non-exported function in the memory unit by locating the memory address of the non-exported function in the table using the identifier, the interceptor software program further comprising interception code for intercepting the non-exported function;
• wherein the non-exported function at least in part lacks compiler produced symbol information in the application software module.

• wherein the memory unit is for storing a plurality of non-exported functions;
• wherein the registry is for storing an identifier corresponding to each of a related group of non-exported functions;
• wherein the table is for storing memory addresses for the related non-exported functions indexed by corresponding identifiers;
• wherein the exported function is adopted to retrieve the corresponding identifiers for the non-exported functions from the registry;
• wherein the interceptor software program is for executing the exported function to retrieve the identifiers, and for locating the corresponding non-exported functions in the memory unit by locating the corresponding memory addresses for the non-exported functions in the registry by locating the identifiers in the table, the interceptor software program further comprising interception code for intercepting the corresponding non-exported functions.
