Hi

I try to translate this from C to Masm32
and i think it is a Struct array and this read out in a while or?

for (i = pBuffer->StructXyz.FirstItem; i <= pBuffer->StructXyz.LastItem + 1; i++) {
int index = i - pBuffer->StructXyz.FirstItem;
if (i <= pBuffer->StructXyz.LastItem) {

pBuffer->StructXyz.pData[index].Address[1]
pBuffer->StructXyz.pData[index].Address[2]
pBuffer->StructXyz.pData[index].Address[3]
}
}

Can any please post an example in masm32

Greets,

It looks like a structure that contains an array of structures, used as a template to access a buffer. I think you are going to need the structure definition to do anything with this. And the following lines are not complete statements:

Code Select


pBuffer->StructXyz.pData[index].Address[1]
pBuffer->StructXyz.pData[index].Address[2]
pBuffer->StructXyz.pData[index].Address[3]

Here is this with structur definition

Code Select


 
typedef struct _p_DATA {
  UCHAR Reserved;
  UCHAR Control  :4;
  UCHAR Adr  :4;
  UCHAR Number;
  UCHAR Reserved1;
  UCHAR Address[4];
} p_DATA, *Pp_DATA;

typedef struct _StructXyz {
  UCHAR Length[2]; 
  UCHAR FirstItem; 
  UCHAR LasttItem; 
  p_DATA pData[MAXIMUM_NUMBER]; 
} StructXyz, *PStructXyz;



StructXyz pBuffer;


for (i = xyz->pBuffer.FirstItem; i <= xyz->pBuffer.LasttItem + 1; i++) {
     int index = i - xyz->pBuffer.FirstItem;
     if (i <= xyz->pBuffer.LasttItem) {
           ;wsprintf for this items "  %02d  %02d  %02d\n",
                     xyz->pBuffer.pData[index].Address[1],
                     xyz->pBuffer.pData[index].Address[2],
                     xyz->pBuffer.pData[index].Address[3]);


         }
}

I hope its better

Put this in a c++ project.
ADD option /FA in the c++ command line nd .... you have it translate in a .asm
