## 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 is 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 is 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 the corresponding implementation-dependent properties.

Valid Usage (Implicit)
• VUID-VkPhysicalDeviceRobustness2PropertiesEXT-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ROBUSTNESS_2_PROPERTIES_EXT
