It's just a unsigned integer value large enough to contain a pointer. So it's _not_ a "pointer to uint". It's "uint that can contain all the bits of a poitner". > and as a consequence ((uintptr_t)p)+1 not different from ((void *)p)+1? No, they're the same. That said, I suspect it might as well be cast to "const char *", and then hopefully you only need one cast. So maybe it could be written as data = (const char *) data + len; instead, and avoid the second cast (because the assignment should be ok, since it's assigning back to a "const void *").
