From the docs I got the package sender object id, packet size and opcode. I also understand the argument formats. From looking at the initial packets sent by the server and correlating with the arguments in wayland.xml ObjectID: 1 (interface "wl_registry"?) Opcode: 1 (event "global"?) Name: uint Interface: string Version: uint I'm guessing that these Names are the objectID to be used for further requests. Am I mixing up object ID and names here or are they the same? What I cannot figure out is how to map a request to an opcode integer. global happened to be the first event in the wl_registry interface, is the order in the xml-file dictating the opcodes? Also if there is any better source for this information such as a specific source code file I'm eager to read it. </body> </html>
