Method: SystemBrowser::Client#start

Defined in:
lib/system_browser/client.rb

#start ⇒ Integer

Note:

@init_pid and @window_pid are two different processes. The

Spawns a new process in a new process group. I really wanted to find the way to spawn the process in the same group. However, when I do that, I cannot send any signals to the window anymore (the app crashes, because the ruby process exits).

client uses @init_id to bootstrap itself and @window_pid is the process that can be used to send signals to the client.

Returns:

  • (Integer) —

    the process ID of the client application

Raises:

  • (RuntimeError)
