◆ ping

void(* xdg_wm_base_listener::ping) (void *data, struct xdg_wm_base *xdg_wm_base, uint32_t serial)

check if the client is alive

The ping event asks the client if it's still alive. Pass the serial specified in the event back to the compositor by sending a "pong" request back with the specified serial. See xdg_wm_base.pong.

Compositors can use this to determine if the client is still alive. It's unspecified what will happen if the client doesn't respond to the ping request, or in what timeframe. Clients should try to respond in a reasonable amount of time. The “unresponsive” error is provided for compositors that wish to disconnect unresponsive clients.

A compositor is free to ping in any way it wants, but a client must always respond to any xdg_wm_base object it created.

Parameters
serialpass this to the pong request
