Linked lists would be a lot of overhead on an already memory-bound
heap. That's not to say that they don't have their place, but often an
array will be the better approach.
I would look into putting the array into a MemHandle and using
MemHandleResize to resize the array. i.e.,
MemHandle array_h;
UInt16* array;
UInt16 array_size;
array_h = MemHandleNew(sizeof(UInt16) * array_size);
/* Handle out of memory condition if array_h is NULL */
array = MemHandleLock(array_h);
for (i=0; i < array_size; ++i)
array[i] = i * 2;
Later, to resize the array:
MemHandleUnlock(array_h);
err = MemHandleResize(array_h, newsize);
/* Handlo out of memory condition if err != errNone */
array = MemHandleLock(array_h);
