I want to sort the records in my PDB. I am trying to get DmInsertionSort to
work for this. I have defined the following Compare function (added lots of
code to make debugging & inspection easier):
Int16 MySort(void* Rec1,void* Rec2,Int16 Other,
SortRecordInfoPtr Rec1SortInfo,SortRecordInfoPtr Rec2SortInfo,
MemHandle AppInfo)
{
TScanDetailStruct* S1; // A struct defining the record structure of my
PDB
TScanDetailStruct* S2;
char* C1 = NULL;
char* C2 = NULL;
// Cast the incoming record pointers to my type to be able to inspect the
record members
S1 = Rec1;
S2 = Rec2;
// Get the record char* members
C1 = S1->ScdPK;
C2 = S2->ScdPK;
return StrCompare(C1,C2);
}
I call the InsertionSort as follows:
Err Error = DmInsertionSort(MyPDBHandle,MySort,0);
When I step into the MySort function, the structures S1,S2 contain garbage.
As far as I am concerned (or according to how I understand the manuals),
they should contain the contents of the 1st & 2nd records the first time.
Any suggestions?
Thanks
