passing references to dlls

[jwilliams]

Hello,

I have a dll that I need to get data out of; the only problem is that it returns data in the parameters I send, not just the "return" value.

I've tried using normal variables with no luck, and now I've tried pointers to dll structures; still nothing.

I'm kind of stuck. Does anyone have any ideas?

Here's an example of my latest attempt (obviously, the dll and function names are modified for posting):

$error_return = DLLStructCreate("short")

DllCall("test.dll","function","none","int",$input,"ptr",DllStructGetPtr($error_return))

MsgBox(0,"","Value: " & DllStructGetData($error_return,1))

I'm not sure how else to pass a reference to a dll in order to get data out via parameters.
