DLLENTRY
Use the DLLENTRY macro to specify the DLL entry point. By default, no entry point is assumed.
For example, when you import programs that were built in the Visual C++ build environment or that use the C run time, you will probably set:
DLLENTRY=_DllMainCRTStartup
See the documentation about the DLL entry point in the Microsoft Win32 SDK to determine what values to use.
