Hi Bjorn, Thanks for the quick reply. On Mon, 2015-03-09 at 21:21 +0100, Bjorn Reese wrote:
Then you can wrap your file descriptor in a posix::stream_descriptor [1] and wait on events using async_read_some() with null_buffers() [2].
An example can be found in [3]. The example assumes that the wrapper does not take ownership of the file descriptor (if it does, then you can omit the non_closing_service.)
Thanks for the suggestion. Unfortunately, though, I don't think async_read_some() is going to work for me. Here is an excerpt from boost/asio/detail/reactive_descriptor_service.hpp: template <typename Handler> void async_read_some(implementation_type& impl, const null_buffers&, Handler handler) { // ... start_op(impl, reactor::read_op, p.p, false, false); // ... } Notice the use of reactor::read_op. I've done a little more digging through the Boost.Asio code, and it looks like, for this application, I need to use reactor::except_op instead. Is there a simple class/function that does this? Or will I have to implement it myself? Kyle
