# VkPushDataInfoEXT(3) Manual Page

## Name

VkPushDataInfoEXT - Structure specifying a push data update operation

Loading… please wait.

## C Specification

The `VkPushDataInfoEXT` structure is defined as:

    // Provided by VK_EXT_descriptor_heap
    typedef struct VkPushDataInfoEXT {
        VkStructureType               sType;
        const void*                   pNext;
        uint32_t                      offset;
        VkHostAddressRangeConstEXT    data;
    } VkPushDataInfoEXT;

## Members

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

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

- `offset` is the start offset of the push data range to update, in units of bytes.

- `data` is the host address range containing the push data to update.

## Description

Valid Usage

- VUID-VkPushDataInfoEXT-offset-11243
  The sum of `offset` and `data.size` must be less than or equal to `maxPushDataSize`

- VUID-VkPushDataInfoEXT-offset-11418
  `offset` must be a multiple of 4

- VUID-VkPushDataInfoEXT-data-11419
  `data.size` must be a multiple of 4

Valid Usage (Implicit)

- VUID-VkPushDataInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PUSH_DATA_INFO_EXT

- VUID-VkPushDataInfoEXT-pNext-pNext
  `pNext` must be `NULL` or a pointer to a valid instance of VkPushConstantBankInfoNV

- VUID-VkPushDataInfoEXT-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique

- VUID-VkPushDataInfoEXT-data-parameter
  `data` must be a valid VkHostAddressRangeConstEXT structure
