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
  • VUID-VkWriteDescriptorSetInlineUniformBlockEXT-dataSize-02222
    dataSize must be an integer multiple of 4

Valid Usage (Implicit)
  • VUID-VkWriteDescriptorSetInlineUniformBlockEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_WRITE_DESCRIPTOR_SET_INLINE_UNIFORM_BLOCK_EXT

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

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