# vkGetPhysicalDeviceCooperativeVectorPropertiesNV(3) Manual Page

## Name

vkGetPhysicalDeviceCooperativeVectorPropertiesNV - Returns properties describing what cooperative vector types are supported

Loading… please wait.

## C Specification

To enumerate the supported cooperative vector type combinations, call:

    // Provided by VK_NV_cooperative_vector
    VkResult vkGetPhysicalDeviceCooperativeVectorPropertiesNV(
        VkPhysicalDevice                            physicalDevice,
        uint32_t*                                   pPropertyCount,
        VkCooperativeVectorPropertiesNV*            pProperties);

## Parameters

- `physicalDevice` is the physical device.

- `pPropertyCount` is a pointer to an integer related to the number of cooperative vector properties available or queried.

- `pProperties` is either `NULL` or a pointer to an array of VkCooperativeVectorPropertiesNV structures.

## Description

If `pProperties` is `NULL`, then the number of cooperative vector properties available is returned in `pPropertyCount`. Otherwise, `pPropertyCount` must point to a variable set by the user to the number of elements in the `pProperties` array, and on return the variable is overwritten with the number of structures actually written to `pProperties`. If `pPropertyCount` is less than the number of cooperative vector properties available, at most `pPropertyCount` structures will be written, and `VK_INCOMPLETE` will be returned instead of `VK_SUCCESS`, to indicate that not all the available cooperative vector properties were returned.

Valid Usage (Implicit)

- VUID-vkGetPhysicalDeviceCooperativeVectorPropertiesNV-physicalDevice-parameter
  `physicalDevice` must be a valid VkPhysicalDevice handle

- VUID-vkGetPhysicalDeviceCooperativeVectorPropertiesNV-pPropertyCount-parameter
  `pPropertyCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetPhysicalDeviceCooperativeVectorPropertiesNV-pProperties-parameter
  If the value referenced by `pPropertyCount` is not `0`, and `pProperties` is not `NULL`, `pProperties` must be a valid pointer to an array of `pPropertyCount` VkCooperativeVectorPropertiesNV structures

Return Codes

On success, this command returns

  - `VK_SUCCESS`

  - `VK_INCOMPLETE`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`
