Abstract
A first dynamic link library (DLL) of a first computing environment, which exports one or more procedures that an application program executing in the first computing environment can call, is replaced with a second DLL that executes in a second computing environment, in a manner that is transparent to the calling application. A source code skeleton of the second DLL is automatically generated based on information contained in a directory of the compiled object code of the first DLL. The exported procedures of the second DLL have interfaces that are identical (from the perspective of the calling application) to the interfaces of the corresponding exported procedures of the first DLL, but the exported procedures of the second DLL comprise native code of the second computing environment. The calling application executing in the first computing environment is the linked dynamically to the exported procedures of the second DLL in the second computing environment in a manner that is transparent to the calling application.
