vkSetEvent

To set the state of an event to signaled from the host, call:

VkResult vkSetEvent(
    VkDevice device,
    VkEvent event);

device is the logical device that owns the event.
event is the event to set.

When vkSetEvent is executed on the host, it defines an event signal operation which sets the event to the signaled state.

If event is already in the signaled state when vkSetEvent is executed, then vkSetEvent has no effect, and no event signal operation occurs.

If a command buffer is waiting for an event to be signaled from the host, the application must signal the event before submitting the command buffer, as described in the queue forward progress section.
