It's not mnemonic, on some machines its just wrong.  NULL is ***NOT***
defined as zero on all machines.  Therefore the software writen with
that assumption will not work on such a machine.  More than likely
the machine will be blamed even though the writer of the software is
to blame.

Almost agreed: but if a negative return code other than -1 is returned
the code doesn't react the same.
