C Specification

The VkDescriptorUpdateTemplateCreateInfo structure is defined as:

typedef struct VkDescriptorUpdateTemplateCreateInfo {
    VkStructureType                           sType;
    const void*                               pNext;
    VkDescriptorUpdateTemplateCreateFlags     flags;
    uint32_t                                  descriptorUpdateEntryCount;
    const VkDescriptorUpdateTemplateEntry*    pDescriptorUpdateEntries;
    VkDescriptorUpdateTemplateType            templateType;
    VkDescriptorSetLayout                     descriptorSetLayout;
    VkPipelineBindPoint                       pipelineBindPoint;
    VkPipelineLayout                          pipelineLayout;
    uint32_t                                  set;
} VkDescriptorUpdateTemplateCreateInfo;

or the equivalent

typedef VkDescriptorUpdateTemplateCreateInfo VkDescriptorUpdateTemplateCreateInfoKHR;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • flags is reserved for future use.

  • descriptorUpdateEntryCount is the number of elements in the pDescriptorUpdateEntries array.

  • pDescriptorUpdateEntries is a pointer to an array of VkDescriptorUpdateTemplateEntry structures describing the descriptors to be updated by the descriptor update template.

  • templateType Specifies the type of the descriptor update template. If set to VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_DESCRIPTOR_SET it can only be used to update descriptor sets with a fixed descriptorSetLayout. If set to VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR it can only be used to push descriptor sets using the provided pipelineBindPoint, pipelineLayout, and set number.

  • descriptorSetLayout is the descriptor set layout the parameter update template will be used with. All descriptor sets which are going to be updated through the newly created descriptor update template must be created with this layout. descriptorSetLayout is the descriptor set layout used to build the descriptor update template. All descriptor sets which are going to be updated through the newly created descriptor update template must be created with a layout that matches (is the same as, or defined identically to) this layout. This parameter is ignored if templateType is not VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_DESCRIPTOR_SET.

  • pipelineBindPoint is a VkPipelineBindPoint indicating whether the descriptors will be used by graphics pipelines or compute pipelines. This parameter is ignored if templateType is not VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR

  • pipelineLayout is a VkPipelineLayout object used to program the bindings. This parameter is ignored if templateType is not VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR

  • set is the set number of the descriptor set in the pipeline layout that will be updated. This parameter is ignored if templateType is not VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR

Description

Valid Usage
  • If templateType is VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_DESCRIPTOR_SET, descriptorSetLayout must be a valid VkDescriptorSetLayout handle

  • If templateType is VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR, pipelineBindPoint must be a valid VkPipelineBindPoint value

  • If templateType is VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR, pipelineLayout must be a valid VkPipelineLayout handle

  • If templateType is VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR, set must be the unique set number in the pipeline layout that uses a descriptor set layout that was created with VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_DESCRIPTOR_UPDATE_TEMPLATE_CREATE_INFO

  • pNext must be NULL

  • flags must be 0

  • pDescriptorUpdateEntries must be a valid pointer to an array of descriptorUpdateEntryCount valid VkDescriptorUpdateTemplateEntry structures

  • templateType must be a valid VkDescriptorUpdateTemplateType value

  • descriptorUpdateEntryCount must be greater than 0

  • Both of descriptorSetLayout, and pipelineLayout that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same VkDevice
