# VkPhysicalDeviceExternalComputeQueuePropertiesNV(3) Manual Page

## Name

VkPhysicalDeviceExternalComputeQueuePropertiesNV - Structure specifying hardware specific information and limits for VK_NV_external_compute_queue functionality

Loading… please wait.

## C Specification

The `VkPhysicalDeviceExternalComputeQueuePropertiesNV` structure is defined as:

    // Provided by VK_NV_external_compute_queue
    typedef struct VkPhysicalDeviceExternalComputeQueuePropertiesNV {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           externalDataSize;
        uint32_t           maxExternalQueues;
    } VkPhysicalDeviceExternalComputeQueuePropertiesNV;

## Members

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

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

- `externalDataSize` is the minimum size of the memory allocation that applications can pass to vkGetExternalComputeQueueDataNV.

- `maxExternalQueues` is the maximum number of external queues that an application can create.

## Description

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceExternalComputeQueuePropertiesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTERNAL_COMPUTE_QUEUE_PROPERTIES_NV`

## See Also
