DLLS using loadlibrary

If I use loadlibrary to load a dll, how would i import its functions

i.e.

dllname = pak.dll

extern "C" void EXPORT SetValue ( float version )

Is the name in the dll :o?

The full procedure run-down would be greatly appreciated :p

thanks

Code:

---

#include <windows.h>

// typedef return_type(calling_convention *pfFunctioName)(arguments)
typedef void(__cdecl *pfSetValue)(float);


int main()
{
        // SetValue is a pointer to a function
        pfSetValue SetValue;

        // Load the dll
        HMODULE hPak = LoadLibrary("pak.dll");

        // Check to make sure it worked...
        if (!hPak)
        {
                MessageBox(NULL, "Failed to Load Library", "Error", MB_OK);
                return 1;
        }
        // Find the address of the function
        // (note that the name may be mangled if this is a c dll)
        SetValue = GetProcAddress(hPak, "SetValue");

        // Check to make sure it worked...
        if (!SetValue)
        {
                MessageBox(NULL, "Failed to Find Address", "Error", MB_OK);
                return 1;
        }
       
        // call the function just like any other function.
        SetValue(42.1);

        return 0;
}
