The lib I try to create provides 'continuations'/'coroutines' for C++ (similiar to features of GO, Python -> call/cc).

I thought Win32 fibers were thread agnostic? e.g. http://blogs.msdn.com/oldnewthing/archive/2010/02/25/9969014.aspx AFAIK the fibers themselves can move between threads. The things you may want to run *on* fibers may have thread affinity and cause problems (e.g. apartment threaded COM objects) but you'd have those problems with any mechanism which moved code calling those things between threads. Can't say that I've ever used fibers, since they only make sense to a very tiny niche which I've never found myself in, but that's my understanding of them. |
