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

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_INITIALIZATION_FAILED

  • VK_ERROR_OUT_OF_HOST_MEMORY
