Sequential record handling question

[Barnett, Phil R]

Does the following code handle memory allocation correctly for skipping
through every record of a table?

Does MemHandleLock() return a memory pointer? Do I need a recP =
MemPtrNew(sizeof(mydataDB)); somewhere?

Thanks.


mydataDBPtr recP;
UInt16   i, numRecs;
MemHandle  recH;

numRecs = DmNumRecords(gDB);

for (i=0; i < numRecs;i++) {
    recH = DmQueryRecord(gDB, i);
    if (recH) {
        recP = (mydataDBPtr)MemHandleLock(recH);
    }
     
    // lots of record oriented code here

    if (recH) {
        MemHandleUnlock(recH);
        MemPtrFree(recP);
    }
}
