Boost Scope Exit

Header <boost/scope_exit.hpp>

Macros

  • BOOST_SCOPE_EXIT(capture_list), BOOST_SCOPE_EXIT_ID(id, capture_list)
  • BOOST_SCOPE_EXIT_TPL(cl), BOOST_SCOPE_EXIT_TPL_ID(id, cl) Used within template code, to workaround some GCC version.
  • BOOST_SCOPE_EXIT_ALL(cl), BOOST_SCOPE_EXIT_ALL_ID(id, cl) Only available for C++11 mode
  • BOOST_SCOPE_EXIT_END, BOOST_SCOPE_EXIT_END_ID(id) On C++11 mode, can be simply ;

The capture_list can be void or comma-separated capture list or sequence of (capture). Each capture can be var, &var, or this_ (for capturing this). For BOOST_SCOPE_EXIT_ALL, a leading & or = capture should be the first one. The _ID version is needed when multiple macros used at the same code line.

Switch

  • BOOST_SCOPE_EXIT_CONFIG_USE_LAMBDAS to force use C++ 11 lambda implementation.
