C Specification

To query the duration of a refresh cycle (RC) for the presentation engine’s display, call:

VkResult vkGetRefreshCycleDurationGOOGLE(
    VkDevice                                    device,
    VkSwapchainKHR                              swapchain,
    VkRefreshCycleDurationGOOGLE*               pDisplayTimingProperties);

Parameters

  • device is the device associated with swapchain.

  • swapchain is the swapchain to obtain the refresh duration for.

  • pDisplayTimingProperties is a pointer to a VkRefreshCycleDurationGOOGLE structure.

Description

Valid Usage (Implicit)
  • device must be a valid VkDevice handle

  • swapchain must be a valid VkSwapchainKHR handle

  • pDisplayTimingProperties must be a valid pointer to a VkRefreshCycleDurationGOOGLE structure

  • Both of device, and swapchain must have been created, allocated, or retrieved from the same VkInstance

Host Synchronization
  • Host access to swapchain must be externally synchronized

Return Codes
On success, this command returns
  • VK_SUCCESS
