This library implements a bidirectional communication interface between applications in different domains, similar to unix sockets. Data can be sent using the byte-oriented libvchan_read/libvchan_write or the packet-oriented libvchan_recv/libvchan_send. Channel setup is done using a client-server model; domain IDs and a port number must be negotiated prior to initialization. The server allocates memory for the shared pages and determines the sizes of the communication rings (which may span multiple pages, although the default places rings and control within a single page). With properly sized rings, testing has shown that this interface provides speed comparable to pipes within a single Linux domain; it is significantly faster than network-based communication.
