Fw: How in the world do I find out the size of a surface in a Wayland client???

[happysmash27]

I am trying to make a Wayland program, and my compositor is Sway. To make it work well, I want my program to use the output size that Sway gives it. The question is... how in the world do I find out what that size actually is??? I can't find it anywhere in the documentation!

The program is written in C, by the way.

Sorry if this message is sent twice, by the way -- I initially couldn't subscribe due to forgetting to enable scripts on the mailing site, making the captcha not work, and the first message doesn't seem to have been sent.
