	results is pointing to a random place in memory; or do you have
'results=(int *)malloc(sizeof(int)*<the number of ints you want>)'
somewhere?  Additionally you will need a 'delete <variable name>'
somewhere.
	Names with underscores (ie _* or __*) are reserved for the
compilers use.  While you will probably get by, it can create problems
(especially if you ever did something like _max); these problems will
typically be very hard to track down.
