vkDestroyImageView

To destroy an image view, call:

void vkDestroyImageView(
    VkDevice device,
    VkImageView imageView,
    const VkAllocationCallbacks* pAllocator);

device is the logical device that destroys the image view.
imageView is the image view to destroy.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.

All submitted commands that refer to imageView must have completed execution

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

If no VkAllocationCallbacks were provided when imageView was created, pAllocator must be NULL

device must be a valid VkDevice handle

If imageView is not VK_NULL_HANDLE, imageView must be a valid VkImageView handle

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

If imageView is a valid handle, it must have been created, allocated, or retrieved from device
