I was writing some code to manage a table the other day. I used
a size_t to keep track of the size of the table, and I defined a
macro SIZE_T_MAX as (size_t)(-1) for making sure the table doesn't
get too large.  Then I suddenly realize that it may not work as
I thought.  An implementation can restrict the size of a data
object to 32 K (is my memory correct here?), but the value of
(size_t)(-1) can at the same time be very large (e.g. ULONG_MAX).
So my question is, is there a way to find out what the maximum
allowable size of a data object  is under an implementation?
