getting data from pointers

Recommended Posts

Hi Folks,

I've been struggling with this problem for days and am turning to you as my last resort.

I am using a DLL provided by a vendor.  I don't have the c source, only the function users guide.

One of the functions I am using returns a type byte*.  Here is the line in the .h file:

const an_Byte* an_GetPrimaryConfigData(an_Chip chip, int* count);

I can call the function like this:

$an_Ptr = DllCall($dll,"int_ptr:cdecl","an_GetPrimaryConfigData","byte",1,"int*",$count_ptr)

Now how do I use an_Ptr to get the data I need.  an_Ptr is pointing to an array of bytes.

 

I know this is probably really stupid but I'm not getting it and I can't find anything here about how to do this.

Thanks in advance for your kind help.

Doug

I just realized I copied the wrong code in my original post.  Here is the correct code:

The c code:

const an_Byte* an_GetPrimaryConfigData(an_Chip chip, int* count);

The AutoIT call:

$bptr = DllCall($dll,"byte*:cdecl","an_GetPrimaryConfigData","byte",1,"int*",$count_ptr)

dougmoran,

What do you see when you do this...

_arraydisplay($bptr)
