I'm writing a GUI library, and I wanted to use the asio concepts in it.
For example, I find it very compelling that every window has a
member-function that returns a io_service::strand to which one
can post messages to the window thread.
This would work well with all mainstream toolkits and the win32 API.
But how would this work with asio implementation?
Can a service be appended to a io_service, and have its own
demultiplexer function control the thread running the run member
function?
The selector_service wouldn't work either I think.
Any way this could be accomplished?
