Dear list,I'm currently writing a Boost.Asio-like interface to librados.hpp. Most things are working like expected, and some things I couldn't figure out from the available docs and code. I have itemized a couple of questions below.
* to avoid allocations done by rados, I'm currently using buffer::create_static() for both reads and writes. I suppose this is ok?
* suppose you have the following code example boost::asio::io_service ios; pool pool( "some pool", ios ); std::string some_data( "this is an example string of data" );pool.async_write_object_at( "hello", 0, boost::asio::buffer( some_data ), &done );
ios.run(); with respect to this interface, I have the following questions:a) the IoCtx's synchronous read() and write() functions return the number of bytes read and written; is there a way to get to this number from AioCompletion? I would like to define the function signature for the callback handler (see 'done' in the example above) something like
void( const boost::system::error_code&, std::size_t ) where the second argument would be the number of bytes transferred.b) is it possible to cancel outstanding asynchronous operations? I.e., have the possibility to implement something like
pool.cancel(); ? TIA, Regards, Rutger -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
