# vkCmdEndQueryIndexedEXT(3) Manual Page

## Name

vkCmdEndQueryIndexedEXT - Ends a query

Loading… please wait.

## C Specification

To end an indexed query after the set of desired drawing or dispatching commands is recorded, call:

    // Provided by VK_EXT_transform_feedback
    void vkCmdEndQueryIndexedEXT(
        VkCommandBuffer                             commandBuffer,
        VkQueryPool                                 queryPool,
        uint32_t                                    query,
        uint32_t                                    index);

## Parameters

- `commandBuffer` is the command buffer into which this command will be recorded.

- `queryPool` is the query pool that is managing the results of the query.

- `query` is the query index within the query pool where the result is stored.

- `index` is the query type specific index.

## Description

The command completes the query in `queryPool` identified by `query` and `index`, and marks it as available.

The `vkCmdEndQueryIndexedEXT` command operates the same as the vkCmdEndQuery command, except that it also accepts a query type specific `index` parameter.

This command defines an execution dependency between other query commands that reference the same query index.

The first synchronization scope includes all commands which reference the queries in `queryPool` indicated by `query` that occur earlier in submission order.

The second synchronization scope includes only the operation of this command.

Valid Usage

- VUID-vkCmdEndQueryIndexedEXT-None-02342
  All queries used by the command must be active

- VUID-vkCmdEndQueryIndexedEXT-query-02343
  `query` must be less than the number of queries in `queryPool`

- VUID-vkCmdEndQueryIndexedEXT-commandBuffer-02344
  `commandBuffer` must not be a protected command buffer

- VUID-vkCmdEndQueryIndexedEXT-query-02345
  If `vkCmdEndQueryIndexedEXT` is called within a render pass instance, the sum of `query` and the number of bits set in the current subpass’s view mask must be less than or equal to the number of queries in `queryPool`

- VUID-vkCmdEndQueryIndexedEXT-queryType-06694
  If the `queryType` used to create `queryPool` was `VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT` or `VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT`, the `index` parameter must be less than `VkPhysicalDeviceTransformFeedbackPropertiesEXT`::`maxTransformFeedbackStreams`

- VUID-vkCmdEndQueryIndexedEXT-queryType-06695
  If the `queryType` used to create `queryPool` was not `VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT` and not `VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT`, the `index` must be zero

- VUID-vkCmdEndQueryIndexedEXT-queryType-06696
  If the `queryType` used to create `queryPool` was `VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT` or `VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT`, `index` must equal the `index` used to begin the query

- VUID-vkCmdEndQueryIndexedEXT-None-07007
  If called within a subpass of a render pass instance, the corresponding `vkCmdBeginQuery`* command must have been called previously within the same subpass

Valid Usage (Implicit)

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

- VUID-vkCmdEndQueryIndexedEXT-queryPool-parameter
  `queryPool` must be a valid VkQueryPool handle

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

- VUID-vkCmdEndQueryIndexedEXT-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support graphics, compute, decode, or encode operations

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

- VUID-vkCmdEndQueryIndexedEXT-commonparent
  Both of `commandBuffer`, and `queryPool` must have been created, allocated, or retrieved from the same VkDevice

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 | Graphics Compute Decode Encode | Action State
