define max length for allocator

Hello everyone,

In MSDN length_error sample,

it uses internal macro _SIZT, other than size_t. I have found in file xmemory, _SIZT is defined to size_t.

So, my questions are

1. why not use size_t directly, why use an internal name (begins with _)?

2. Do we have to use _SIZT when we define a customized allocator?

thanks in advance,
