Boost.Coroutine

boost.coroutine

boost.coroutine provides templates for generalized subroutines which allow multiple entry points for suspending and resuming execution at certain locations. It preserves the local state of execution and allows re-entering subroutines more than once (useful if state must be kept across function calls).

Coroutines can be viewed as a language-level construct providing a special kind of control flow.

In contrast to threads, which are pre-emptive, coroutines switches are cooperative (programmer controls when a switch will happen). The kernel is not involved in the coroutine switches.

Note that boost.coroutine is deprecated - boost.coroutine2 is its successor. If you are forced to use a pre-C++11 compiler you should still use boost.coroutine.
