# vkCmdSetDescriptorBufferOffsets2EXT(3) Manual Page

## Name

vkCmdSetDescriptorBufferOffsets2EXT - Setting descriptor buffer offsets in a command buffer

## C Specification

To set descriptor buffer offsets in a command buffer, call:

Warning | This functionality is superseded by VK_EXT_descriptor_heap. See Legacy Functionality for more information.

    // Provided by VK_KHR_maintenance6 with VK_EXT_descriptor_buffer
    void vkCmdSetDescriptorBufferOffsets2EXT(
        VkCommandBuffer                             commandBuffer,
        const VkSetDescriptorBufferOffsetsInfoEXT*  pSetDescriptorBufferOffsetsInfo);

## Parameters

- `commandBuffer` is the command buffer in which the descriptor buffer offsets will be set.

- `pSetDescriptorBufferOffsetsInfo` is a pointer to a `VkSetDescriptorBufferOffsetsInfoEXT` structure.

## Description

Valid Usage

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-commandBuffer-11295
  If `commandBuffer` is a secondary command buffer, it must have begun with VkCommandBufferInheritanceDescriptorHeapInfoEXT::`pSamplerHeapBindInfo` equal to `NULL`

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-commandBuffer-11296
  If `commandBuffer` is a secondary command buffer, it must have begun with VkCommandBufferInheritanceDescriptorHeapInfoEXT::`pResourceHeapBindInfo` equal to `NULL`

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-descriptorBuffer-09470
  The `descriptorBuffer` feature must be enabled

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-pSetDescriptorBufferOffsetsInfo-09471
  Each bit in `pSetDescriptorBufferOffsetsInfo->stageFlags` must be a stage supported by the `commandBuffer`’s parent `VkCommandPool`’s queue family

Valid Usage (Implicit)

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-commandBuffer-parameter
  `commandBuffer` must be a valid VkCommandBuffer handle

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-pSetDescriptorBufferOffsetsInfo-parameter
  `pSetDescriptorBufferOffsetsInfo` must be a valid pointer to a valid VkSetDescriptorBufferOffsetsInfoEXT structure

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-commandBuffer-recording
  `commandBuffer` must be in the recording state

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support VK_QUEUE_COMPUTE_BIT, VK_QUEUE_DATA_GRAPH_BIT_ARM, or VK_QUEUE_GRAPHICS_BIT operations

- VUID-vkCmdSetDescriptorBufferOffsets2EXT-videocoding
  This command must only be called outside of a video coding scope

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

- Host access to the `VkCommandPool` that `commandBuffer` was allocated from must be externally synchronized

Command Properties

Command Buffer Levels | Render Pass Scope | Video Coding Scope | Supported Queue Types | Command Type
--- | --- | --- | --- | ---
Primary Secondary | Both | Outside | VK_QUEUE_COMPUTE_BIT VK_QUEUE_DATA_GRAPH_BIT_ARM VK_QUEUE_GRAPHICS_BIT | State

Conditional Rendering

vkCmdSetDescriptorBufferOffsets2EXT is not affected by conditional rendering
