Subject: Boost coroutine/context libraries From: Gregory Laird Date: Tue, 17 Jan 2017 17:10:57 -0800 Newsgroup: gmane.comp.lib.boost.user

I am trying to write a cooperative task scheduler in c++ and I have discovered the boost context and coroutine libraries. I have written these sorts of schedulers many times in assembly language so I appreciate the issues in the methodology. I have written lots of c code but am less versed in c++.

I have been trying to find some straightforward examples of the libraries use without a lot of extraneous c++ language elements (e.g. binds, lambdas, etc.). I did find one example

http://stackoverflow.com/questions/11716291/boost-context-class

that is very nice, but it will not compile now with the current boost library. I get an error saying that boost::context::fcontext_t has been removed from the public api.

Could someone direct me to some examples that demonstrate the context or coroutine functionality that would be easier to understand.

Maybe this helps - very basic coroutine "scheduler" example: https://github.com/daniel-j-h/coroutine-scheduler/blob/master/main.cc I would go with Boost.Coroutine2 / Boost.Coroutine directly instead of the lower-level context featuers.

I want to write a scheduler that is very similar to the example listed above where coroutines yeild back to a main caller which then chooses the next coroutine to continue its processing.
