If I call this function exactly 19 times it will always
crash on the 19th with an access low memory error
and it will crash on this line
strArray[recordindex] = MemPtrNew(StrLen(p) + 1);
I have tried usinf the debugger but can not see what is wrong
Am I failing to release some memory on exit of the function
search_database()
{
Char *p;
Char **strArray = NULL;
Char* strLines = NULL;
Err err;
UInt16 index = 0, recordindex = 0, nRecordIndex = 0;
FormPtr form1;
ListType *lsp1;
MemHandle Rh;
form1 = FrmGetActiveForm(); // get active form
err = Open(); // routine to open database
if(!err)
{
lsp1 = FrmGetObjectPtr(form1, FrmGetObjectIndex(form1, frmList1)); //
get id of list control
nRecordIndex = DmNumRecords(dbPtr); // number of records
strArray = MemPtrNew(nRecordIndex * sizeof(Char *));
for(index =0; index < nRecordIndex; index++) // lets index through
database
{
Rh = DmQueryRecord(dbPtr, index); // lets query each record
p = (Char *) MemHandleLock(Rh); // lets lock each record
if( 0 == StrNCaselessCompare( letter, p, 1) ) //compare first letter of
first field
{
strArray[recordindex] = MemPtrNew(StrLen(p) + 1);
StrCopy(strArray[recordindex], p);
recordindex++;
}
MemHandleUnlock(Rh); // unlock each record
}
LstSetListChoices(lsp1,strArray,recordindex);
LstDrawList( lsp1 );
err = CloseDB();
}
return true;
}
