# vkCreateCudaFunctionNV(3) Manual Page

## Name

vkCreateCudaFunctionNV - Creates a new CUDA function object

Loading… please wait.

## C Specification

To create a CUDA function, call:

    // Provided by VK_NV_cuda_kernel_launch
    VkResult vkCreateCudaFunctionNV(
        VkDevice                                    device,
        const VkCudaFunctionCreateInfoNV*           pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkCudaFunctionNV*                           pFunction);

## Parameters

- `device` is the logical device that creates the shader module.

- `pCreateInfo` is a pointer to a VkCudaFunctionCreateInfoNV structure.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

- `pFunction` is a pointer to a VkCudaFunctionNV handle in which the resulting CUDA function object is returned.

## Description

Valid Usage (Implicit)

- VUID-vkCreateCudaFunctionNV-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkCreateCudaFunctionNV-pCreateInfo-parameter
  `pCreateInfo` must be a valid pointer to a valid VkCudaFunctionCreateInfoNV structure

- VUID-vkCreateCudaFunctionNV-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkCreateCudaFunctionNV-pFunction-parameter
  `pFunction` must be a valid pointer to a VkCudaFunctionNV handle

- VUID-vkCreateCudaFunctionNV-device-queuecount
  The device must have been created with at least `1` queue

Return Codes

On success, this command returns

  - VK_SUCCESS

On failure, this command returns

  - VK_ERROR_INITIALIZATION_FAILED

  - VK_ERROR_OUT_OF_HOST_MEMORY

  - VK_ERROR_UNKNOWN

  - VK_ERROR_VALIDATION_FAILED
