# VkTensorCopyARM(3) Manual Page

## Name

VkTensorCopyARM - Structure specifying an tensor copy region

Loading… please wait.

## C Specification

The `VkTensorCopyARM` structure is defined as:

    // Provided by VK_ARM_tensors
    typedef struct VkTensorCopyARM {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           dimensionCount;
        const uint64_t*    pSrcOffset;
        const uint64_t*    pDstOffset;
        const uint64_t*    pExtent;
    } VkTensorCopyARM;

## Members

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

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

- `dimensionCount` is the number of elements in the `pSrcOffset`, `pDstOffset` and `pExtent` arrays.

- `pSrcOffset` is `NULL` or an array of size `dimensionCount` providing an offset into the source tensor. When `pSrcOffset` is `NULL`, the offset into the source tensor is `0` in all dimensions.

- `pDstOffset` is `NULL` or an array of size `dimensionCount` providing an offset into the destination tensor. When `pDstOffset` is `NULL`, the offset into the destination tensor is `0` in all dimensions.

- `pExtent` is `NULL` or an array of size `dimensionCount` providing the number of elements to copy in each dimension. When `pExtent` is `NULL`, the number of elements to copy is taken as the total number of elements in each dimension of the source tensor.

## Description

Valid Usage (Implicit)

- VUID-VkTensorCopyARM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_TENSOR_COPY_ARM`

- VUID-VkTensorCopyARM-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkTensorCopyARM-pSrcOffset-parameter
  If `pSrcOffset` is not `NULL`, `pSrcOffset` must be a valid pointer to an array of `dimensionCount` `uint64_t` values

- VUID-VkTensorCopyARM-pDstOffset-parameter
  If `pDstOffset` is not `NULL`, `pDstOffset` must be a valid pointer to an array of `dimensionCount` `uint64_t` values

- VUID-VkTensorCopyARM-pExtent-parameter
  If `pExtent` is not `NULL`, `pExtent` must be a valid pointer to an array of `dimensionCount` `uint64_t` values

- VUID-VkTensorCopyARM-dimensionCount-arraylength
  `dimensionCount` must be greater than `0`
