When I setup memory pool beginning with 0x0000, malloc doesn't work.

Ding Curie

When:

init_mempool(0x0000, 1024);
p = malloc(10);
malloc always returns NULL.
But when:
init_mempool(0x2000, 1024);
p = malloc(10);
p gets a valid address.
Why does this happen?
Thanks.

    I did have a look at the source code. But at the first glance, the code is so complicated that I wasn't patient enough to read it through. Now I know this was not the case. Maybe the macro and typedef make things that. But it seems that there is no need to read it any more -- I think I've known where the question lies. Thanks anyway.
