I'm using VC++ 2010 Ultimate and I'm running a Windows 7 x64 machine.
I have a function declared to be a dll export (
__declspec(dllexport) ) and it builds without error or warning, but when I try to load that function with
GetProcAddress it returns NULL. I've looked inside the .exp file VC++ generates and the function is in there, but when I look inside the .dll file it generates the function isn't in there, and I have no idea why.
Also, I can't use implicit linking for this function because this function has to be loaded from more then one seperate DLL.
This is how I'm declaring the function:
DLL_EXPORT void *InterfaceFactory( char *pInterfaceName );
This is how I'm trying to load the function:
HMODULE pDLL = LoadLibrary( "vsys.dll" ); void *pOut = GetProcAddress( pDLL, "InterfaceFactory" );
When I run this code pDLL isn't NULL after I load the DLL so I don't know why it's not able to find InterfaceFactory.
BTW the code for exporting the function and loading the function are in different projects (and DLLs) inside Visual Studio.
