| | This interface works in conjunction with IFilterStreamSocketConnections to allow stream filters to issue new read and write events. Any filter that either can swallow data buffers (by not passing on calls to the next filter in the chain) or that generates data buffers (passing data to the next filter in the chain when that data wasn't generated by a previous layer in the chain) should always use this interface to pass data buffers to the next layer in the chain. Failure to do so will affect any buffer sequencing that may (or may not) be occurring. A filter can specify that its own sequence counter is used by requesting one from the socket allocator and then by passing the sequence id to the relevant calls. If a filter only ever injects new data into a stream then it can use the socket's own sequence counter and calls to the methods that don't take an explicit sequence id. More...
