Error checking

[Edward P. Ross]

Just to make sure I'm on the right page - for the code snippet below, how would I make 
sure this is robust enough not to fail?
(i.e. how would I want to write this so that it would fail gracefully if there isn't 
enough memory to allocate the handle?)

Thanks,
Ed.

MemHandle h;
 UInt16  index = 0;

 DmSeekRecordInCategory(gClientsDB, &index, (UInt16) itemNum, dmSeekForward, 
dmAllCategories);

 h = DmQueryRecord(gClientsDB, index);

   if (h) {
     skelClientsDBType  *p = (skelClientsDBType *) MemHandleLock(h);
     DrawCharsToFitWidth(p->Name, bounds);
     MemHandleUnlock(h);
   }
