   I am having trouble building a DLL via what appears   
   to be the documented process, and I thought I would   
   use this opportunity to find out what a DLL actually is.   
      
   If I have two independent source files, foo.c and bar.c,   
   each with one function in it, ie foo() and bar()   
   respectively, is this something that is suitable to put   
   into a DLL, or is there an expectation that it all be   
   linked in to a single executable?   
      
   I ask because I have this code in dllcrt.c:   
      
   BOOL WINAPI DllMainCRTStartup(HINSTANCE hinstDll,   
                                 DWORD fdwReason,   
                                 LPVOID lpvReserved)   
   {   
       BOOL bRet;   
      
       /* DllMain() is optional, so it would be good to handle that case too. */   
       bRet = DllMain(hinstDll, fdwReason, lpvReserved);   
      
       return (bRet);   
   }   
      
   (apparently written by Alica).   
      
   Although the code works fine with gccwin, when I   
   tried to build my own kernel32.dll using the old   
   version of Visual Studio I have installed, I got a   
   link error which was resolved by adding an   
   underscore to the above name.   
      
   But the DLL being produced is very small and doesn't   
   contain the functions I want, and that is confirmed   
   by the link map.   
      
   Any idea what a DLL actually is?   
      
   Thanks. Paul.
