C Specification

To destroy a device, call:

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


  • device is the logical device to destroy.

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


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.


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

  • Host access to all VkQueue objects received from device must be externally synchronized
