# VkExternalComputeQueueCreateInfoNV(3) Manual Page

## Name

VkExternalComputeQueueCreateInfoNV - Structure specifying configuration parameters for external compute queue creation

Loading… please wait.

## C Specification

The `VkExternalComputeQueueCreateInfoNV` structure is defined as:

    // Provided by VK_NV_external_compute_queue
    typedef struct VkExternalComputeQueueCreateInfoNV {
        VkStructureType    sType;
        const void*        pNext;
        VkQueue            preferredQueue;
    } VkExternalComputeQueueCreateInfoNV;

## Members

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

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

- `preferredQueue` is a `VkQueue` supporting graphics commands.

## Description

When creating a `VkExternalComputeQueueNV`, the `preferredQueue` field is a strong scheduling hint as to which `VkQueue` Vulkan graphics workloads will be submitted to with the expectation that execution will overlap with execution of work submitted by the external API.

Valid Usage (Implicit)

- VUID-VkExternalComputeQueueCreateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXTERNAL_COMPUTE_QUEUE_CREATE_INFO_NV`

- VUID-VkExternalComputeQueueCreateInfoNV-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkExternalComputeQueueCreateInfoNV-preferredQueue-parameter
  `preferredQueue` must be a valid VkQueue handle
