wl_interface(3)                     Wayland                    wl_interface(3)

NAME
       wl_interface

SYNOPSIS
       #include <wayland-util.h>

   Data Fields
       const char * name
       int version
       int method_count
       const struct wl_message * methods
       int event_count
       const struct wl_message * events

Detailed Description
       Protocol object interface

       A wl_interface describes the API of a protocol object defined in the
       Wayland protocol specification. The protocol implementation uses a
       wl_interface within its marshalling machinery for encoding client
       requests.

       The name of a wl_interface is the name of the corresponding protocol
       interface, and version represents the version of the interface. The
       members method_count and event_count represent the number of methods
       (requests) and events in the respective wl_message members.

       For example, consider a protocol interface foo, marked as version 1,
       with two requests and one event.

       <interface name="foo" version="1">
         <request name="a"></request>
         <request name="b"></request>
         <event name="c"></event>
       </interface>

       Given two wl_message arrays foo_requests and foo_events, a wl_interface
       for foo might be:

       struct wl_interface foo_interface = {
               "foo", 1,
               2, foo_requests,
               1, foo_events
       };

       Note
           The server side of the protocol may define interface implementation
           types that incorporate the term interface in their name. Take care
           to not confuse these server-side structs with a wl_interface
           variable whose name also ends in interface. For example, while the
           server may define a type struct wl_foo_interface, the client may
           define a struct wl_interface wl_foo_interface.
