| Special Mathematical Functions | An Independent Technical Report | |||||||||
| Decimal Floating Point | An Independent Technical Report | |||||||||
| Thread Pools | TR2? | |||||||||
| Read/Write mutex | Likely for TR2; likely model is Boost.Thread's shared_mutex | |||||||||
| Lock-Free Data Structures | ||||||||||
| File System Library | To be in TR2; model is Boost.Filesystem | |||||||||
| Date/time (beyond C++0x's std::chrono) | TR2?; likely model is Boost.Date_Time | |||||||||
| Networking Library | TR2?; likely model is Boost.Asio | |||||||||
| lexical_cast | Functionality available in Boost.Conversion | |||||||||
| Improved IO (e.g., faster, memory-mapped) | Boost.Interprocess supports memory-mapped files | |||||||||
| Programmer-Controlled GC | ||||||||||
| Range-Based Algorithms | TR2?; likely model is Boost.Range | |||||||||
| volatile with acquire/release semantics | ||||||||||
