# VkExternalComputeQueueDataParamsNV(3) Manual Page

## Name

VkExternalComputeQueueDataParamsNV - Structure specifying parameters for implementation-specific data retrieval from the external compute queue

Loading… please wait.

## C Specification

The `VkExternalComputeQueueDataParamsNV` structure is defined as:

    // Provided by VK_NV_external_compute_queue
    typedef struct VkExternalComputeQueueDataParamsNV {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           deviceIndex;
    } VkExternalComputeQueueDataParamsNV;

## Members

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

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

- `deviceIndex` is the index of the device within a device group that the data is being queried for. This is ignored if device groups are not utilized.

## Description

Valid Usage (Implicit)

- VUID-VkExternalComputeQueueDataParamsNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXTERNAL_COMPUTE_QUEUE_DATA_PARAMS_NV`

- VUID-VkExternalComputeQueueDataParamsNV-pNext-pNext
  `pNext` must be `NULL`
