I am surprised that this ever works. In addition to the problem with
'inv' that Bob McKenzie mentioned, DmNewRecord() expects its second
argument to be a pointer to a UInt16, and you passed it 0, which it
probably treats as a NULL pointer. Also, the third argument should be
the size of the new record in bytes. The size isn't a problem if you
are going to resize the record in PackInventory(), but I think the NULL
pointer definitely is a problem. If you want it to add the new record
at the beginning of the database, you should do this:
UInt16 index = 0;
VoidHand h = DmNewRecord(inventoryDB, &index, 1);
and if you want to add the new record at the end of the database, do
this:
UInt16 index = dmMaxRecordIndex;
VoidHand h = DmNewRecord(inventoryDB, &index, 1);
