DllMain

Description:
This shows how to prevent any of the CRT code from executing in a DLL. Usefull for making those tiny DLLs even smaller, and a bit faster.
 
Code:
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, 
  LPVOID lpvReserved ) {

     /* ... */

     return TRUE;
}

extern "C" BOOL __stdcall _DllMainCRTStartup( 
  HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) {

     return DllMain( hinstDLL, fdwReason, lpvReserved );

}
