1boost.coroutine 2=============== 3 4boost.coroutine provides templates for generalized subroutines which allow multiple entry points for 5suspending and resuming execution at certain locations. It preserves the local state of execution and 6allows re-entering subroutines more than once (useful if state must be kept across function calls). 7 8Coroutines can be viewed as a language-level construct providing a special kind of control flow. 9 10In contrast to threads, which are pre-emptive, coroutines switches are cooperative (programmer controls 11when a switch will happen). The kernel is not involved in the coroutine switches. 12 13Note that boost.coroutine is deprecated - boost.coroutine2 is its successor. 14If you are forced to use a pre-C++11 compiler you should still use boost.coroutine. 15
