Hi!
If I'm correct then the first "serious" implementation of unique_ptr for C++03 was written by Howard Hinnant, which was later adopted to Boost.Interprocess library.
Unfortunately, I suppose not many people are aware of the fact that unique_ptr for C++03 is available in Boost. Even worse, I know people who are aware of it but who are afraid of using it just because it is provided by Boost.Interprocess, not by Boost.SmartPtr.
Therefore, here's my proposal: - boost::interprocess::unique_ptr could be pulled into the top-level boost namespace - Boost.SmartPtr could provide a header file for unique_ptr that would pull the implementation from Boost.Interprocess; such a header file could also be placed in the top-level boost directory so that it could be accessed more easily - boost::unique_ptr could be documented in the documentation for Boost.SmartPtr library, providing use cases, emulation limitations etc.
I believe that would make unique_ptr for C++03 available to wider audience.
What do you think about this idea?
I think if the unique_ptr in interprocess doesn't depend on the rest of interprocess, or can be easily made stand-alone, then it should just be moved into smart_ptr. I don't want the smart_ptr library to depend on interprocess. That would be weird. Interprocess can then #include unique_ptr and import it into its namespace with a using directive for back compat. -- Eric Niebler Boost.org
