boos.task has a bounded and a unbounded buffer - unfortunately I've to wait until boost.context will pass the mini-review before I can submit the refactored version of boost.task. Oliver -------- Original-Nachricht --------

Hi all,
I seem to have come across a producer/consumer situation a few times now, and everytime I do, I seem to want a slightly different functionality for a bounded buffer-kind of class that is not generally provided. I am looking for such a class that is also efficient for large amounts of data, and so I wonder if there does already exists a class in boost to efficiently push work between producers and consumers when they are running in different threads, i.e., that is

Hi Robert,
Thanks for your reply. Just to clarify, that example was actually the one I was referring to my mail:
"There is a bounded_buffer example given to implement such a thing with the circular buffer. It does exactly what I suggest, but I assume it is not so efficient for pushing large amounts of data over, as each individual object requires a push, thus a lock implemented as in bounded_buffer, and involves unnecessary updates of the counters (involving a decrement() each time) on each push, which is not necessary if you know you are pushing a number of elements at once. I assume this could be fixed by wrapping the insert(range) method instead of the individual push functions."
Apart from not providing an efficient push of a range, it misses the write_end() functionality that I mentioned. Hence the question if that would be something which is generally useful, or if it is just in my case.
Eitherway, I agree that the bounded_buffer example is on itself already useful in many situations.
Regards, André
