## Name

vkDestroyOpticalFlowSessionNV - Destroy optical flow session object

Loading… please wait.

## C Specification

To destroy an optical flow session object, call:

    // Provided by VK_NV_optical_flow
    void vkDestroyOpticalFlowSessionNV(
        VkDevice                                    device,
        VkOpticalFlowSessionNV                      session,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the device that was used for the creation of the optical flow session.

- `session` is the optical flow session to be destroyed.

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

## Description

Valid Usage (Implicit)

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

- VUID-vkDestroyOpticalFlowSessionNV-session-parameter
  `session` must be a valid VkOpticalFlowSessionNV handle

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

- VUID-vkDestroyOpticalFlowSessionNV-session-parent
  `session` must have been created, allocated, or retrieved from `device`
