Re: DllMain vs. DllMain

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

In theory on some future non NT-based implementation of Win32 HINSTANCE (==
HMODULE) may not be void * and not compatible with HANDLEs. In practice this
is almost unthinkable. Lots of Win32 code assumes HMODULE is a pointer to
the beginning of DLL in memory. Lots of Win32 code (including VC CRT)
assumes that HANDLE is void *. Together these facts mean that for the
foreseeable future HANDLE is going to be freely interchangeable with
HMODULE.

Note that on NT based systems HANDLEs are designed to be compatible with
HINSTANCEs. AFAIK the native NT API functions that deal
with DLLs (LdrXXX family) are all defined in terms of HANDLEs.
