VkWriteIndirectExecutionSetShaderEXT(3)

# VkWriteIndirectExecutionSetShaderEXT(3) Manual Page

## Name

VkWriteIndirectExecutionSetShaderEXT - Struct specifying shader object update information for an indirect execution set

## C Specification

The `VkWriteIndirectExecutionSetShaderEXT` structure is defined as:

    // Provided by VK_EXT_device_generated_commands with VK_EXT_shader_object
    typedef struct VkWriteIndirectExecutionSetShaderEXT {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           index;
        VkShaderEXT        shader;
    } VkWriteIndirectExecutionSetShaderEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `index` is the element of the set to update

- `shader` is the shader to store in the indirect execution set

## Description

Shaders need not be stored in the Indirect Execution Set according to their stage. The only restriction for shader indices within a set is that the value of the index must be less than the maximum number of shaders in the set.

Valid Usage

- VUID-VkWriteIndirectExecutionSetShaderEXT-index-11031
  `index` must be less than `VkIndirectExecutionSetShaderInfoEXT`::`maxShaderCount`

- VUID-VkWriteIndirectExecutionSetShaderEXT-shader-11032
  `shader` must have been created with VK_SHADER_CREATE_INDIRECT_BINDABLE_BIT_EXT

- VUID-VkWriteIndirectExecutionSetShaderEXT-pInitialShaders-11033
  A shader created with the same VkShaderStageFlagBits must have been passed in the `VkIndirectExecutionSetShaderInfoEXT`::`pInitialShaders` array

- VUID-VkWriteIndirectExecutionSetShaderEXT-index-11034
  `index` must not be in use by submitted command buffers

Valid Usage (Implicit)

- VUID-VkWriteIndirectExecutionSetShaderEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_WRITE_INDIRECT_EXECUTION_SET_SHADER_EXT

- VUID-VkWriteIndirectExecutionSetShaderEXT-shader-parameter
  `shader` must be a valid VkShaderEXT handle
