If you are using Visual Studio, you should have a tool called "Dependency
walker" installed (called "Depends" in the start menu, under Visual
Studio -> Tools)
Start it and open the DLL you are using (gsdkpcsc.dll)
Among other things, you should now see the exact function names. See if your
function declaration matches the entry you see in the dependency walker. If
not, try the wording from the dependency walker. Alternatively you can also
use the "ordinal" number (leftmost column) and write it like e.g. Declare
Function [...] Alias "#33", where 33 would be the decimal ordinal number of
the function you want.
