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);

Parameters

  • device is the logical device that owns the event.

  • event is the event to reset.

Description

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.

Valid Usage
  • VUID-vkResetEvent-event-03821
    There must be an execution dependency between vkResetEvent and the execution of any vkCmdWaitEvents that includes event in its pEvents parameter

  • VUID-vkResetEvent-event-03822
    There must be an execution dependency between vkResetEvent and the execution of any vkCmdWaitEvents2KHR that includes event in its pEvents parameter

  • VUID-vkResetEvent-event-03823
    event must not have been created with VK_EVENT_CREATE_DEVICE_ONLY_BIT_KHR

Valid Usage (Implicit)
  • VUID-vkResetEvent-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkResetEvent-event-parameter
    event must be a valid VkEvent handle

  • VUID-vkResetEvent-event-parent
    event must have been created, allocated, or retrieved from device

Host Synchronization
  • Host access to event must be externally synchronized

Return Codes
On success, this command returns
  • VK_SUCCESS

On failure, this command returns
  • VK_ERROR_OUT_OF_DEVICE_MEMORY
