# vkDestroyDevice(3) Manual Page

## Name

vkDestroyDevice - Destroy a logical device

## C Specification

To destroy a device, call:

    void vkDestroyDevice(
        VkDevice                                    device,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device to destroy.

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

## Description

To ensure that no work is active on the device, vkDeviceWaitIdle can be used to gate the destruction of the device. Prior to destroying a device, an application is responsible for destroying/freeing any Vulkan objects that were created using that device as the first parameter of the corresponding `vkCreate*` or `vkAllocate*` command.

| Note The lifetime of each of these objects is bound by the lifetime of the `VkDevice` object. Therefore, to avoid resource leaks, it is critical that an application explicitly free all of these resources prior to calling `vkDestroyDevice`.

Valid Usage

- All child objects created on `device` must have been destroyed prior to destroying `device`

- If `VkAllocationCallbacks` were provided when `device` was created, a compatible set of callbacks must be provided here

- If no `VkAllocationCallbacks` were provided when `device` was created, `pAllocator` must be `NULL`

Valid Usage (Implicit)

- If `device` is not `NULL`, `device` must be a valid VkDevice handle

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

Host Synchronization

- Host access to `device` must be externally synchronized
