Note how MemMove specifies void * parameters, while func2 specifies MemPtr parameters.
This tells you that func2 requires pointers to dynamically allocated memory blocks,
while MemMove does not. Thus MemMove cannot possibly safely deallocate memory passed
to it, while func2 may (and in the above implementation, does).

It's a single-to-noise ratio issue; the quality of questions has decreased while the
bandwidth required to conclude them has increased. Not surprisingly, this annoys most
people, because it degrades the value of the forum. Especially when 90% of the answers
can easily be found in 1.) the programming documentation (API reference and companion
docs), 2.) the Palm Knowledgebase, and/or 3.) the sample code.
