vkGetPhysicalDeviceDisplayPlanePropertiesKHR

Images are presented to individual planes on a display. Devices must support at least one plane on each display. Planes can be stacked and blended to composite multiple images on one display. Devices may support only a fixed stacking order and fixed mapping between planes and displays, or they may allow arbitrary application-specified stacking orders and mappings between planes and displays. To query the properties of device display planes, call:

VkResult vkGetPhysicalDeviceDisplayPlanePropertiesKHR(
    VkPhysicalDevice physicalDevice,
    uint32_t* pPropertyCount,
    VkDisplayPlanePropertiesKHR* pProperties);

• physicalDevice is a physical device.
• pPropertyCount is a pointer to an integer related to the number of display planes available or queried, as described below.
• pProperties is either NULL or a pointer to an array of VkDisplayPlanePropertiesKHR structures.

If pProperties is NULL, then the number of display planes available for physicalDevice is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the application to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If the value of pPropertyCount is less than the number of display planes for physicalDevice, at most pPropertyCount structures will be written.
