is there anyway to get which compositor did the client "wl_display" object connected?

Hi,

I think you could get the socket fd and fstat() it, but aside that I
don't recall anything. There might not even be a file if the connection
was created with socketpair(). I'm not sure if you can somehow get the
pid of the server process, maybe you can. There is no protocol for
identifying the server, but if this is about an app-internal server,
you could easily write tiny a protocol extension to identify your
internal server from anything else.

What do you want to use it for?


Thanks,
pq
