vkRegisterDeviceEventEXT(3)

Name

vkRegisterDeviceEventEXT - Signal a fence when a device event occurs

C Specification

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

// Provided by VK_EXT_display_control
VkResult vkRegisterDeviceEventEXT(
    VkDevice                                    device,
    const VkDeviceEventInfoEXT*                 pDeviceEventInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkFence*                                    pFence);

Parameters

  • device is a logical device on which the event may occur.

  • pDeviceEventInfo is a pointer to a VkDeviceEventInfoEXT 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.

Description

Valid Usage (Implicit)

  • VUID-vkRegisterDeviceEventEXT-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkRegisterDeviceEventEXT-pDeviceEventInfo-parameter
    pDeviceEventInfo must be a valid pointer to a valid VkDeviceEventInfoEXT structure

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

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

Return Codes
Success

  • VK_SUCCESS

Failure

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_UNKNOWN

  • VK_ERROR_VALIDATION_FAILED
