C++ -> Pure HELP!!!

[Num3]

I'm writing a CDR burning program
I already make iso images, and now i'm writing the burner part

Here's the problem...

Code: Select all

// get disc info 
// -- parameters:
// -- 1st parm: handle of the window of the calling program
// -- 2nd parm: host adapter Id (usually 0)
// -- 3rd parm: CD-R writer SCSI Id
// -- 4th parm: CD-R writer SCSI LUN (usually 0)
   char* info;
   info = pfnFFDiscInfo ( Application -> Handle, 0, 2, 0 );
   MessageBox ( 0, info, "Disc Information Block:", MB_SYSTEMMODAL );

In pure should be:

Code: Select all

 ...(snip)
  If CallFunctionFast(*aspistart)
    Debug "Aspi Layer - OK"

    Delay(1000) ; Little delay before crashing

    x=CallFunctionFast(*aspiinfo,"", 0,2, 0 )
    Debug x
    
    CallFunctionFast(*aspistop)
    Debug "Aspi Layer - Closed"
  EndIf
  CloseLibrary(0)
EndIf

But the program always crashes when i call *aspiinfo function !

Can anyone help???

I think, your cut the examples to heavy:

but, when i read the parameter-List:
i would this

Code: Select all

x=CallFunctionFast(*aspiinfo,"", 0,2, 0 )
debug x

correct to this

Code: Select all

x=CallFunctionFast(*aspiinfo,windowid(), 0,2, 0 )
debug peeks(x)

Thanks GPI, but that didn't make it work either....

Here's the full code in C++ and Purebasic:
