Re: [Boost-users] [lexical_cast] Why isn't boost::lexical_cast bijective?

2 John: I wanted to convert a hexadecimal address string (like "FFFFF880AABBCCDD") to void*. It works vice versa so why doesn't this work this way? 2 Paolo: I don't know how to specify that the integer is in hexadecimal form then. Thank you all for your replies.

I think we use something like that in that case: long(boost::addressof(obj))?

Perhaps using the integer value as address?

Why this works:

boost::lexical_caststd::string((void *) 42UL)

and this throws:

boost::lexical_cast(boost::lexical_caststd::string((void*) 42UL))

while converting void* to std::string and vice versa works perfectly using std:: streams?

What is converting a std::string object to a void* supposed to mean?
