C Specification

To create a fence that will be signaled when an event occurs on a VkDisplayKHR object, call:

// Provided by VK_EXT_display_control
VkResult vkRegisterDisplayEventEXT(
    VkDevice                                    device,
    VkDisplayKHR                                display,
    const VkDisplayEventInfoEXT*                pDisplayEventInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkFence*                                    pFence);


  • device is a logical device associated with display

  • display is the display on which the event may occur.

  • pDisplayEventInfo is a pointer to a VkDisplayEventInfoEXT structure describing the event of interest to the application.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pFence is a pointer to a handle in which the resulting fence object is returned.


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

  • VUID-vkRegisterDisplayEventEXT-display-parameter
    display must be a valid VkDisplayKHR handle

  • VUID-vkRegisterDisplayEventEXT-pDisplayEventInfo-parameter
    pDisplayEventInfo must be a valid pointer to a valid VkDisplayEventInfoEXT structure

  • VUID-vkRegisterDisplayEventEXT-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkRegisterDisplayEventEXT-pFence-parameter
    pFence must be a valid pointer to a VkFence handle

  • VUID-vkRegisterDisplayEventEXT-commonparent
    Both of device, and display must have been created, allocated, or retrieved from the same VkPhysicalDevice

Return Codes
