C Specification

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

// Provided by VK_VERSION_1_0
VkResult vkResetEvent(
    VkDevice                                    device,
    VkEvent                                     event);


  • device is the logical device that owns the event.

  • event is the event to reset.


When vkResetEvent is executed on the host, it defines an event unsignal operation which resets the event to the unsignaled state.

If event is already in the unsignaled state when vkResetEvent is executed, then vkResetEvent has no effect, and no event unsignal operation occurs.

    event must not be waited on by a vkCmdWaitEvents command that is currently executing
