# vkGetPipelineExecutableInternalRepresentationsKHR(3) Manual Page

## Name

vkGetPipelineExecutableInternalRepresentationsKHR - Get internal representations of the pipeline executable

Loading… please wait.

## C Specification

Each pipeline executable may have one or more text or binary internal representations associated with it which are generated as part of the compile process. These may include the final shader assembly, a binary form of the compiled shader, or the shader compiler’s internal representation at any number of intermediate compile steps. To query the internal representations associated with a pipeline executable, call:

    // Provided by VK_KHR_pipeline_executable_properties
    VkResult vkGetPipelineExecutableInternalRepresentationsKHR(
        VkDevice                                    device,
        const VkPipelineExecutableInfoKHR*          pExecutableInfo,
        uint32_t*                                   pInternalRepresentationCount,
        VkPipelineExecutableInternalRepresentationKHR* pInternalRepresentations);

## Parameters

- `device` is the device that created the pipeline.

- `pExecutableInfo` describes the pipeline executable being queried.

- `pInternalRepresentationCount` is a pointer to an integer related to the number of internal representations available or queried, as described below.

- `pInternalRepresentations` is either `NULL` or a pointer to an array of VkPipelineExecutableInternalRepresentationKHR structures.

## Description

If `pInternalRepresentations` is `NULL`, then the number of internal representations associated with the pipeline executable is returned in `pInternalRepresentationCount`. Otherwise, `pInternalRepresentationCount` must point to a variable set by the application to the number of elements in the `pInternalRepresentations` array, and on return the variable is overwritten with the number of structures actually written to `pInternalRepresentations`. If `pInternalRepresentationCount` is less than the number of internal representations associated with the pipeline executable, at most `pInternalRepresentationCount` structures will be written, and `VK_INCOMPLETE` will be returned instead of `VK_SUCCESS`, to indicate that not all the available representations were returned.

While the details of the internal representations remain implementation-dependent, the implementation should order the internal representations in the order in which they occur in the compiled pipeline with the final shader assembly (if any) last.

Valid Usage

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pipelineExecutableInfo-03276
  The `pipelineExecutableInfo` feature must be enabled

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pipeline-03277
  The `pipeline` member of `pExecutableInfo` must have been created with `device`

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pipeline-03278
  The `pipeline` member of `pExecutableInfo` must have been created with `VK_PIPELINE_CREATE_CAPTURE_INTERNAL_REPRESENTATIONS_BIT_KHR`

Valid Usage (Implicit)

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pExecutableInfo-parameter
  `pExecutableInfo` must be a valid pointer to a valid VkPipelineExecutableInfoKHR structure

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pInternalRepresentationCount-parameter
  `pInternalRepresentationCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetPipelineExecutableInternalRepresentationsKHR-pInternalRepresentations-parameter
  If the value referenced by `pInternalRepresentationCount` is not `0`, and `pInternalRepresentations` is not `NULL`, `pInternalRepresentations` must be a valid pointer to an array of `pInternalRepresentationCount` VkPipelineExecutableInternalRepresentationKHR structures

Return Codes

On success, this command returns

  - `VK_SUCCESS`

  - `VK_INCOMPLETE`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`
