# VkPhysicalDeviceInlineUniformBlockFeatures(3) Manual Page

## Name

VkPhysicalDeviceInlineUniformBlockFeatures - Structure describing inline uniform block features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceInlineUniformBlockFeatures` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPhysicalDeviceInlineUniformBlockFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           inlineUniformBlock;
        VkBool32           descriptorBindingInlineUniformBlockUpdateAfterBind;
    } VkPhysicalDeviceInlineUniformBlockFeatures;

or the equivalent

    // Provided by VK_EXT_inline_uniform_block
    typedef VkPhysicalDeviceInlineUniformBlockFeatures VkPhysicalDeviceInlineUniformBlockFeaturesEXT;

## Members

This structure describes the following features:

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

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

## Description

- `inlineUniformBlock` indicates whether the implementation supports inline uniform block descriptors. If this feature is not enabled, `VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK` must not be used.

- `descriptorBindingInlineUniformBlockUpdateAfterBind` indicates whether the implementation supports updating inline uniform block descriptors after a set is bound. If this feature is not enabled, `VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT` must not be used with `VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK`.

If the `VkPhysicalDeviceInlineUniformBlockFeatures` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceInlineUniformBlockFeatures`, it must add an instance of the structure, with the desired feature members set to `VK_TRUE`, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceInlineUniformBlockFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INLINE_UNIFORM_BLOCK_FEATURES`
