functionSLSMainConnectionIDcprobed

The calling process's connection to the window server. Almost every other call takes this connection id as its first argument. Non-zero once the process has a window-server connection; a launchd job with no GUI session gets 0.

let lib = dlopen("/System/Library/PrivateFrameworks/SkyLight.framework/Versions/A/SkyLight", RTLD_NOW)
typealias SLSMainConnectionID = @convention(c) () -> Int32
let cid = unsafeBitCast(dlsym(lib, "SLSMainConnectionID")!, to: SLSMainConnectionID.self)()
// -> 565531 on the probing machine; the value differs per process
