For a 'long' 10 characters is likely to be not enough (long max
is 9223372036854775808 which has 19 chars, and you should reserve
additional one for the sign and one for the terminating null), so
I would at least recommend using char[21].
with char[10] your function becomes a big hole in your security,
as it can easily be misused to write 10 bytes of freely
selectable garbage behind your allocated memory.
But as you want to avoid the gc, security might not be a goal for
you, so continue living in the 1970's.
