# VkPhysicalDeviceShaderObjectPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceShaderObjectPropertiesEXT - Structure describing shader object properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderObjectPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_shader_object
    typedef struct VkPhysicalDeviceShaderObjectPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint8_t            shaderBinaryUUID[VK_UUID_SIZE];
        uint32_t           shaderBinaryVersion;
    } VkPhysicalDeviceShaderObjectPropertiesEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

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

- `shaderBinaryUUID` is an array of `VK_UUID_SIZE` `uint8_t` values representing a universally unique identifier for one or more implementations whose shader binaries are guaranteed to be compatible with each other.

- `shaderBinaryVersion` is an unsigned integer incremented to represent backwards compatible differences between implementations with the same `shaderBinaryUUID`.

## Description

The purpose and usage of the values of this structure are described in greater detail in Binary Shader Compatibility.

If the `VkPhysicalDeviceShaderObjectPropertiesEXT` 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-VkPhysicalDeviceShaderObjectPropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_OBJECT_PROPERTIES_EXT`
