## Name

VkIndirectCommandsPushConstantTokenEXT - Structure specifying layout token info for a single push constant command token

Loading… please wait.

## C Specification

The `VkIndirectCommandsPushConstantTokenEXT` structure specifies the layout token info for `VK_INDIRECT_COMMANDS_TOKEN_TYPE_PUSH_CONSTANT_EXT` and `VK_INDIRECT_COMMANDS_TOKEN_TYPE_SEQUENCE_INDEX_EXT` tokens.

    // Provided by VK_EXT_device_generated_commands
    typedef struct VkIndirectCommandsPushConstantTokenEXT {
        VkPushConstantRange    updateRange;
    } VkIndirectCommandsPushConstantTokenEXT;

## Members

- `updateRange` is the push constant range that will be updated by the token.

## Description

The `stageFlags` member of `updateRange` is ignored.

Valid Usage

- VUID-VkIndirectCommandsPushConstantTokenEXT-updateRange-11132
  `updateRange` must be contained within the push constant info used by VkIndirectCommandsLayoutCreateInfoEXT

- VUID-VkIndirectCommandsPushConstantTokenEXT-size-11133
  If the token type is `VK_INDIRECT_COMMANDS_TOKEN_TYPE_SEQUENCE_INDEX_EXT`, the `size` member of `updateRange` must be 4

Valid Usage (Implicit)

- VUID-VkIndirectCommandsPushConstantTokenEXT-updateRange-parameter
  `updateRange` must be a valid VkPushConstantRange structure
