Compilation Method:

Save the preceding files as sources, makefile, and DLL. CPP, DLL. def then open the wdk compiling environment and switch to the directory where the files are stored. Execute build-C to generate a DLL. DLL file, which contains an export function add

Note: The _ stdcall call Convention is used to reference the export function of a dynamic library.
