vkDestroyImageView

vkDestroyImageView is a function in the Vulkan graphics API used to destroy an image view object. Image views are Vulkan objects that represent a view into an image, allowing it to be sampled in a shader or used as a render target. When an image view is no longer needed, it should be destroyed to free up associated resources.

The function signature is VkResult vkDestroyImageView(VkDevice device, VkImageView imageView, const VkAllocationCallbacks* pAllocator). The first argument, device, is the logical device handle that the image view was created on. The second argument, imageView, is the handle to the image view object to be destroyed. The third argument, pAllocator, is an optional pointer to a VkAllocationCallbacks structure that can be used to provide custom memory allocation callbacks. If this is NULL, the default allocator will be used.

Upon successful destruction, vkDestroyImageView returns VK_SUCCESS. If the imageView handle is invalid or if the image view is still in use by any Vulkan operations, the function may return an error code. It is crucial to ensure that an image view is not being used before calling vkDestroyImageView to avoid undefined behavior or crashes. Destroying an image view does not affect the underlying image object itself. The image object must be destroyed separately if it is no longer required.
