 Event version numbers are exposed as
 [INTERFACE_NAME]_[EVENT_NAME]_SINCE_VERSION for example wl_output.scale
 will have the version macro WL_OUTPUT_SCALE_SINCE_VERSION.

Yeah, that's a little more readable I guess.  This and previous patches
applied, thanks.

[PATCH wayland 6/6] scanner: Generate macros for getting the 'since' version of an event

2014-05-08 Thread Jonas Ådahl 
This could be useful for compositors who need to be able to not send
events if the client bound a version lower than the newest provided.

Event version numbers are exposed as
[INTERFACE_NAME]_[EVENT_NAME]_SINCE_VERSION for example wl_output.scale
will have the version macro WL_OUTPUT_SCALE_SINCE_VERSION.
