vkGetPhysicalDeviceSurfaceFormats2KHR

To query the supported swapchain format tuples for a surface, call:

VkResult vkGetPhysicalDeviceSurfaceFormats2KHR(
    VkPhysicalDevice physicalDevice,
    const VkPhysicalDeviceSurfaceInfo2KHR* pSurfaceInfo,
    uint32_t* pSurfaceFormatCount,
    VkSurfaceFormat2KHR* pSurfaceFormats);

• physicalDevice is the physical device that will be associated with the swapchain to be created, as described for vkCreateSwapchainKHR.
• pSurfaceInfo is a pointer to a VkPhysicalDeviceSurfaceInfo2KHR structure describing the surface and other fixed parameters that would be consumed by vkCreateSwapchainKHR.
• pSurfaceFormatCount is a pointer to an integer related to the number of format tuples available or queried, as described below.
• pSurfaceFormats is either NULL or a pointer to an array of VkSurfaceFormat2KHR structures.

vkGetPhysicalDeviceSurfaceFormats2KHR behaves similarly to vkGetPhysicalDeviceSurfaceFormatsKHR, with the ability to be extended via pNext chains.

If pSurfaceFormats is NULL, then the number of format tuples supported for the given surface is returned in pSurfaceFormatCount. Otherwise, pSurfaceFormatCount must point to a variable set by the application to the number of elements in the pSurfaceFormats array, and on return the variable is overwritten with the number of structures actually written to pSurfaceFormats. If the value of pSurfaceFormatCount is less than the number of format tuples supported, at most pSurfaceFormatCount structures will be written, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available values were returned.
