* @brief Dispatch events from a Wayland event queue
|
|
*
|
|
* Dispatch events from a given Wayland display event queue, including calling event handlers, and flush out any
|
|
* requests the event handlers may have written. Specification of a timeout allows the wait to be bounded. If any
|
|
* events are already pending dispatch (have been read from the display by another thread or event queue), they
|
|
* will be dispatched and the function will return immediately, without waiting for new events to arrive.
|
|
*
|
|
* @param display Wayland display to dispatch events from
|
|
* @param queue Event queue to dispatch events from; other event queues will not have their handlers called from
|
|
* within this function
|
|
* @param timeout Maximum time to wait for events to arrive, in milliseconds. A negative value means infinite timeout.
|
|
* @return 1 if one or more events were dispatched on this queue, 0 if the timeout was reached without any
|
|
* events being dispatched, or -1 on error.
