vkGetEventStatus

To query the state of an event from the host, call:

VkResult vkGetEventStatus(
    VkDevice device,
    VkEvent event);

• device is the logical device that owns the event.
• event is the handle of the event to query.

Upon success, vkGetEventStatus returns the state of the event object with the following return codes:

If a vkCmdSetEvent or vkCmdResetEvent command is in a command buffer that is in the pending state, then the value returned by this command may immediately be out of date.

The state of an event can be updated by the host. The state of the event is immediately changed, and subsequent calls to vkGetEventStatus will return the new state. If an event is already in the requested state, then updating it to the same state has no effect.
