## Name

VkPhysicalDeviceRobustness2PropertiesEXT - Structure describing robust buffer access properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceRobustness2PropertiesEXT` structure is defined as:

    // Provided by VK_EXT_robustness2
    typedef struct VkPhysicalDeviceRobustness2PropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkDeviceSize       robustStorageBufferAccessSizeAlignment;
        VkDeviceSize       robustUniformBufferAccessSizeAlignment;
    } VkPhysicalDeviceRobustness2PropertiesEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `robustStorageBufferAccessSizeAlignment` is the number of bytes that the range of a storage buffer descriptor is rounded up to when used for bounds-checking when `robustBufferAccess2` is enabled. This value must be either 1 or 4.

- `robustUniformBufferAccessSizeAlignment` is the number of bytes that the range of a uniform buffer descriptor is rounded up to when used for bounds-checking when `robustBufferAccess2` is enabled. This value must be a power of two in the range [1, 256].

## Description

If the `VkPhysicalDeviceRobustness2PropertiesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceRobustness2PropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ROBUSTNESS_2_PROPERTIES_EXT`
