# VkWriteDescriptorSetInlineUniformBlockEXT(3) Manual Page

## Name

VkWriteDescriptorSetInlineUniformBlockEXT - Structure specifying inline uniform block data

Loading… please wait.

## C Specification

If the `descriptorType` member of VkWriteDescriptorSet is `VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXT` then the data to write to the descriptor set is specified through a `VkWriteDescriptorSetInlineUniformBlockEXT` structure included in the `pNext` chain of `VkWriteDescriptorSet`.

The `VkWriteDescriptorSetInlineUniformBlockEXT` structure is defined as:

    // Provided by VK_EXT_inline_uniform_block
    typedef struct VkWriteDescriptorSetInlineUniformBlockEXT {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           dataSize;
        const void*        pData;
    } VkWriteDescriptorSetInlineUniformBlockEXT;

## Members

- `sType` is the type of this structure.

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

- `dataSize` is the number of bytes of inline uniform block data pointed to by `pData`.

- `pData` is a pointer to `dataSize` number of bytes of data to write to the inline uniform block.

## Description

Valid Usage

- `dataSize` must be an integer multiple of `4`

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_WRITE_DESCRIPTOR_SET_INLINE_UNIFORM_BLOCK_EXT`

- `pData` must be a valid pointer to an array of `dataSize` bytes

- `dataSize` must be greater than `0`
