C Specification

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

The VkWriteDescriptorSetInlineUniformBlock structure is defined as:

// Provided by VK_VERSION_1_3
typedef struct VkWriteDescriptorSetInlineUniformBlock {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           dataSize;
    const void*        pData;
} VkWriteDescriptorSetInlineUniformBlock;

or the equivalent

// Provided by VK_EXT_inline_uniform_block
typedef VkWriteDescriptorSetInlineUniformBlock VkWriteDescriptorSetInlineUniformBlockEXT;


  • sType is a VkStructureType value identifying 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.


Valid Usage
  • VUID-VkWriteDescriptorSetInlineUniformBlock-dataSize-02222
    dataSize must be an integer multiple of 4

Valid Usage (Implicit)
  • VUID-VkWriteDescriptorSetInlineUniformBlock-sType-sType

  • VUID-VkWriteDescriptorSetInlineUniformBlock-pData-parameter
    pData must be a valid pointer to an array of dataSize bytes

  • VUID-VkWriteDescriptorSetInlineUniformBlock-dataSize-arraylength
    dataSize must be greater than 0
