Re: [Boost-users] Casting this pointer to a number

I'd like to provide a function with an unique identifier:

Why? What is it going to do with the ID? Why not make the ID a void* pointer? And what semantics does this "unique identification" have? Once an object is deleted, another new'd object may get its address; I can hardly qualify that as "unique ID".

I guess another question is: should I bother replacing this old-style cast, maybe there is a better way to approach this situation in general?

reinterpret_cast. although, that's long and painful to type at every function invocation (so is the old-style cast), so I'd redefine f() as void f(void *pv) { size_t uid = reinterpret_cast(pv); ... }
