Comparing functions

[DevidEspenschied]

Zitat von Razor:

So why is it there var pdata:cardinal and in the omcdrv.pas its var pdata:dword; dont really really get it; and plus why cant i call that function.... :shock:

Just had a look at your unit.

It seems that Delphi in general (e.g. my Delphi 2007 Pro as well as your version 7) doesn't always update the function parameters for the internal programmer help, which is displayed after entering k.IPCIIORef.

You can be sure that GetPCIRDWord doesn't contain a cardinal value, just a DWord value. If you are confused by the hint of the programmer help, use a DWord variable, compile it and have a look at the bottom messages list. Would the function really need a cardinal variable, there should be a message entry.

Had the same problem here too and Delphi needs sometimes a complete code compilation (sometimes 2 or 3 times) to know, that a variable is a DWord and not a Cardinal. But that must have mean, that a cardinal type was there previously.

To be sure just search the entire unit after a cardinal value - you won't find some. That is the acnowledgement that there isn't one. Hope that helps...
