I have stepped through it several times. If I comment out the lines, like bellow,
the DmWrite line works, but then it is just writes over the first part of the chunk
over an over. The first offset increment of pos only moves it two bytes. I will go
through the part that allocates the memory again, but the chunk should be the right
size. In any event the first write is failing which is only 2 or 4 bytes, and much
more than that has been allocated for the entire chunk.
The problem seems to happen as soon as I increment pos.
UInt16 PackRecord(CRecipientNodePtr Head, void * pDest)
{
UInt16 offset = 0;
CRecipientNodePtr Cur = Head;
CRecipientType Recip = {0};
Char * pos;
CRecipientNodeListType Header = {0};
// Skip Header
offset += sizeof (CRecipientNodeListType);
pos = (Char *)pDest;
//pos += offset;
while (Cur != NULL)
{
Header.Count++;
UnpackRecord(Cur->Recip, &Recip);
offset += PackRecord(&Recip, (CRecipientPackedPtr)pos);
//pos += offset;
Cur = Cur->Next;
}
I was thinking I might be using the variable wrong, i.e. incrementing the var instead
of the pointer, or something.
Thanks,
