Overview of this book

Vulkan is the next generation graphics API released by the Khronos group. It is expected to be the successor to OpenGL and OpenGL ES, which it shares some similarities with such as its cross-platform capabilities, programmed pipeline stages, or nomenclature. Vulkan is a low-level API that gives developers much more control over the hardware, but also adds new responsibilities such as explicit memory and resources management. With it, though, Vulkan is expected to be much faster. This book is your guide to understanding Vulkan through a series of recipes. We start off by teaching you how to create instances in Vulkan and choose the device on which operations will be performed. You will then explore more complex topics such as command buffers, resources and memory management, pipelines, GLSL shaders, render passes, and more. Gradually, the book moves on to teach you advanced rendering techniques, how to draw 3D scenes, and how to improve the performance of your applications. By the end of the book, you will be familiar with the latest advanced techniques implemented with the Vulkan API, which can be used on a wide range of platforms.

Destroying a command pool

When all command buffers allocated from a given pool are not used any more, and we also don't need the pool, we can safely destroy it.

How to do it...

  1. Take the handle of a logical device and store it in a variable of type VkDevice named logical_device.
  2. Use a handle of the pool that should be destroyed to initialize a variable of type VkCommandPool named command_pool.
  3. Call vkDestroyCommandPool( logical_device, command_pool, nullptr ), for which provide the handles of the logical device and the command pool, and a nullptr value.
  4. For safety reasons, assign the VK_NULL_HANDLE value to the command_pool variable.

How it works...
