Introduction

This is the page concerning which subset of the standard features could be used in this project.

Several C++0x features are used since 2011-05-03, build 206. These features are also in ISO C++11(ISO/IEC 14882:2011).

C++11 is now default to conform. All C++03 features conflicted with C++11 are forbidden.

However, the codebase is still largely based on C++03(ISO/IEC 14882:2003).

Following are the features introduced explicitly to clearify dependences on the language implementations.

Details

C++11 core language features and headers below now could be used.

See Documentation::Designation[Designation.txt, zh-CN] @ 1.3.2.1 .

New headers from C++11 used:

  • <array> (since b218[2011-06-14])
  • <chrono> (since b291[2012-03-07])
  • <forward_list> (since b218[2011-06-14])
  • <type_traits> (since b206[2011-05-03])
  • <tuple> (since b206[2011-05-03])
  • <system_error> (since b476[2014-02-16])
  • <unordered_map> (since b206[2011-05-03])
  • <unordered_set> (since b206[2011-05-03])

For all implementations supporting multithreading, these headers are also used:

  • <atomic> (since b328[2011-07-25]; for platform MinGW32 since b299[2013-04-08])
  • <condition_variable> (since b328[2011-07-25]; for platform MinGW32 since b299[2013-04-08])
  • <future> (since b520[2014-07-23])
  • <mutex> (since b328[2011-07-25]; for platform MinGW32 since b299[2013-04-08])
  • <thread> (since b328[2011-07-25]; for platform MinGW32 since b299[2013-04-08])

Note: LWG1360 specified single-threaded program should be able to use <atomic>, and resolved by N3256. However, the current YSLib doesn't require it for single-threaded programs.
