I have a question regarding pointers and handles... When exiting my application, CW
says that I have 1 memory leak. I was
under the impression that for each handle I have, I should free it, and for each
pointer, I should free it when I am done with
it. The code below is what is giving me the problem. It only happens if I have
records in the DB, i.e. the code makes it to
the 'for loop'.
I put the MemPtrFree(itemList); and MemHandleFree(recordH); in the code (see the
bottom of this email) but when I do, I get a
fatal error. My question is, where should I be doing the cleanup for this handle?
Thanks,
Ed.
void frmTypesInitForm() {
FormPtr frmP = FrmGetActiveForm();
ListType *lstP;
UInt16 theCategory = dmAllCategories;
UInt16 totalItems, i;
UInt16 recordNum = 0;
UInt16 pos = 9;
MemHandle recordH;
Char **itemList;
// List box
lstP = (ListType *) FrmGetObjectPtr(frmP, FrmGetObjectIndex(frmP, frmTypesList));
// Get number of records in database
if(gSRCatDB != NULL){
totalItems = DmNumRecordsInCategory(gSRCatDB, theCategory);
itemList = (Char **) MemPtrNew(totalItems * 16);
// Code to visit every record:
for (i = 0; i < totalItems; i++) {
recordH = DmQueryNextInCategory (gSRCatDB, &pos, theCategory);
if (recordH) {
skelSRCatDBType * p = (skelSRCatDBType *) MemHandleLock(recordH);
itemList[i] = (char *) &(p->ExType);
MemHandleUnlock(recordH);
pos++;
}
}
LstSetListChoices(lstP, itemList, totalItems);
//MemPtrFree(itemList);
//MemHandleFree(recordH);
}
}
