1boost.coroutine2 2=============== 3 4boost.coroutine2 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 13boost.coroutine2 requires C++11! 14Note that boost.coroutine2 is the successor of the deprectated boost.coroutine. 15
