# VkBindIndexBufferIndirectCommandNV(3) Manual Page

## Name

VkBindIndexBufferIndirectCommandNV - Structure specifying input data for a single index buffer command token

Loading… please wait.

## C Specification

The `VkBindIndexBufferIndirectCommandNV` structure specifies the input data for the `VK_INDIRECT_COMMANDS_TOKEN_TYPE_INDEX_BUFFER_NV` token.

    // Provided by VK_NV_device_generated_commands
    typedef struct VkBindIndexBufferIndirectCommandNV {
        VkDeviceAddress    bufferAddress;
        uint32_t           size;
        VkIndexType        indexType;
    } VkBindIndexBufferIndirectCommandNV;

## Members

- `bufferAddress` specifies a physical address of the VkBuffer used as index buffer.

- `size` is the byte size range which is available for this operation from the provided address.

- `indexType` is a VkIndexType value specifying how indices are treated. Instead of the Vulkan enum values, a custom `uint32_t` value can be mapped to an VkIndexType by specifying the `VkIndirectCommandsLayoutTokenNV`::`pIndexTypes` and `VkIndirectCommandsLayoutTokenNV`::`pIndexTypeValues` arrays.

## Description

Valid Usage

- VUID-VkBindIndexBufferIndirectCommandNV-None-02946
  The buffer’s usage flag from which the address was acquired must have the `VK_BUFFER_USAGE_INDEX_BUFFER_BIT` bit set

- VUID-VkBindIndexBufferIndirectCommandNV-bufferAddress-02947
  The `bufferAddress` must be aligned to the `indexType` used

- VUID-VkBindIndexBufferIndirectCommandNV-None-02948
  Each element of the buffer from which the address was acquired and that is non-sparse must be bound completely and contiguously to a single `VkDeviceMemory` object

Valid Usage (Implicit)

- VUID-VkBindIndexBufferIndirectCommandNV-indexType-parameter
  `indexType` must be a valid VkIndexType value
