/*!
@page vulkan Vulkan guide
@tableofcontents
This guide is intended to fill the gaps between the Vulkan documentation and the
rest of the GLFW documentation and is not a replacement for either.
To develop for Vulkan you should install an SDK for your platform, for example
the [LunarG Vulkan SDK](http://lunarg.com/vulkan-sdk/). Apart from the headers
and libraries, it also provides the validation layers necessary for development.
GLFW itself does not need a Vulkan SDK to enable support for Vulkan. However,
any Vulkan-specific test and example programs are built only if the CMake files
find the LunarG SDK.
@section vulkan_include Including the Vulkan and GLFW header files
To include the Vulkan header, define `GLFW_INCLUDE_VULKAN` before including the
GLFW header.
@code
#define GLFW_INCLUDE_VULKAN
#include <GLFW/glfw3.h>
@endcode
If you want to include the Vulkan header from a custom location or use your own
custom Vulkan header then you need to include them before the GLFW header.
@code
#include <custom/path/vulkan.h>
#include <GLFW/glfw3.h>
@endcode
Unless a Vulkan header is included, either by the GLFW header or above it, any
GLFW functions that use Vulkan types will not be declared.
The `VK_USE_PLATFORM_*_KHR` macros do not need to be defined for the Vulkan part
of GLFW to work.
@section vulkan_support Querying for Vulkan support
If you are loading the Vulkan loader dynamically instead of linking directly
against it, you can check for the availability of a loader with @ref
glfwVulkanSupported.
@code
if (glfwVulkanSupported())
{
// Vulkan is available, at least for compute
}
@endcode
This function returns `GLFW_TRUE` if the Vulkan loader was found. This check is
performed by @ref glfwInit.
If no loader was found, calling any other Vulkan related GLFW function will
generate a @ref GLFW_API_UNAVAILABLE error.
@subsection vulkan_proc Querying Vulkan function pointers
To load any Vulkan core or extension function from the found loader, call @ref
glfwGetInstanceProcAddress.
@code
PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)
glfwGetInstanceProcAddress(instance, "vkCreateDevice");
@endcode
This is equivalent to calling `vkGetInstanceProcAddr`. If that fails, the
function falls back to a platform-specific query of the Vulkan loader (i.e.
`dlsym` or `GetProcAddress`). If that also fails, the function returns `NULL`.
For more information about `vkGetInstanceProcAddr`, see the Vulkan
documentation.
Vulkan also provides `vkGetDeviceProcAddr` for loading device-specific versions
of Vulkan function. This function can be retrieved from an instance with @ref
glfwGetInstanceProcAddress.
@code
PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)
glfwGetInstanceProcAddress(instance, "vkGetDeviceProcAddr");
@endcode
Device-specific functions may execute a little bit faster, due to not having to
dispatch internally based on the device passed to them. For more information
about `vkGetDeviceProcAddr`, see the Vulkan documentation.
@section vulkan_ext Querying required Vulkan extensions
To do anything useful with Vulkan you need to create an instance. If you want
to use Vulkan to render to a window, you must enable the instance extensions
GLFW requires to create Vulkan surfaces.
To query the instance extensions required, call @ref
glfwGetRequiredInstanceExtensions.
@code
int count;
const char** extensions = glfwGetRequiredInstanceExtensions(&count);
@endcode
These extensions must all be enabled when creating instances that are going to
be passed to @ref glfwGetPhysicalDevicePresentationSupport and @ref
glfwCreateWindowSurface. The set of extensions will vary depending on platform
and may also vary depending on graphics drivers and other factors.
If it fails it will return `NULL` and Vulkan window surface creation will not be
possible. You may still use Vulkan for off-screen rendering and compute work.
The returned array will always contain `VK_KHR_surface`, so if you don't
require any additional extensions you can pass this list directly to the
`VkInstanceCreateInfo` struct.
@code
VkInstanceCreateInfo ici;
memset(&ici, 0, sizeof(ici));
ici.enabledExtensionCount = count;
ici.ppEnabledExtensionNames = extensions;
...
@endcode
Additional extensions may be required by future versions of GLFW. You should
check whether any extensions you wish to enable are already in the returned
array, as it is an error to specify an extension more than once in the
`VkInstanceCreateInfo` struct.
@section vulkan_present Querying for Vulkan presentation support
Not every Vulkan queue family of every device can present images to surfaces.
To check whether a specific queue family of a physical device supports image
presentation without first having to create a window and surface, call @ref
glfwGetPhysicalDevicePresentationSupport.
@code
if (glfwGetPhysicalDevicePresentationSupport(instance, physical_device, queue_family_index))
{
// Queue family supports image presentation
}
@endcode
The `VK_KHR_surface` extension also provides the
`vkGetPhysicalDeviceSurfaceSupportKHR` function, which performs the same test on
an existing Vulkan surface.
@section vulkan_window Creating the window
Unless you will be using OpenGL or OpenGL ES in addition to Vulkan, there is no
need to create a context for that window. You can disable context creation by
setting the [GLFW_CLIENT_API](@ref window_hints_ctx) hint to `GLFW_NO_API`.
@code
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
GLFWwindow* window = glfwCreateWindow(640, 480, "Window Title", NULL, NULL);
@endcode
See @ref context_less for more information.
@section vulkan_surface Creating a Vulkan window surface
You can create a Vulkan surface (as defined by the `VK_KHR_surface` extension)
for a GLFW window with @ref glfwCreateWindowSurface.
@code
VkSurfaceKHR surface;
VkResult err = glfwCreateWindowSurface(instance, window, NULL, &surface);
if (err)
{
// Window surface creation failed
}
@endcode
It is your responsibility to destroy the surface. GLFW does not destroy it for
you. Call `vkDestroySurfaceKHR` function from the same extension to destroy it.

/*! @brief Creates a Vulkan surface for the specified window.
*
* This function creates a Vulkan surface for the specified window.
*
* If the Vulkan loader was not found at initialization, this function returns
* `VK_ERROR_INITIALIZATION_FAILED` and generates a @ref GLFW_API_UNAVAILABLE
* error. Call @ref glfwVulkanSupported to check whether the Vulkan loader was
* found.
*
* If the required window surface creation instance extensions are not
* available or if the specified instance was not created with these extensions
* enabled, this function returns `VK_ERROR_EXTENSION_NOT_PRESENT` and
* generates a @ref GLFW_API_UNAVAILABLE error. Call @ref
* glfwGetRequiredInstanceExtensions to check what instance extensions are
* required.
*
* The window surface must be destroyed before the specified Vulkan instance.
* It is the responsibility of the caller to destroy the window surface. GLFW
* does not destroy it for you. Call `vkDestroySurfaceKHR` to destroy the
* surface.
*
* @param[in] instance The Vulkan instance to create the surface in.
* @param[in] window The window to create the surface for.
* @param[in] allocator The allocator to use, or `NULL` to use the default
* allocator.
* @param[out] surface Where to store the handle of the surface. This is set
* to `VK_NULL_HANDLE` if an error occurred.
* @return `VK_SUCCESS` if successful, or a Vulkan error code if an
* [error](@ref error_handling) occurred.
*
* @errors Possible errors include @ref GLFW_NOT_INITIALIZED, @ref
* GLFW_API_UNAVAILABLE and @ref GLFW_PLATFORM_ERROR.
*
* @remarks If an error occurs before the creation call is made, GLFW returns
* the Vulkan error code most appropriate for the error. Appropriate use of
* @ref glfwVulkanSupported and @ref glfwGetRequiredInstanceExtensions should
* elminiate almost all occurences of these errors.
*
* @thread_safety This function may be called from any thread. For
* synchronization details of Vulkan objects, see the Vulkan specification.
*
* @sa @ref vulkan_surface
* @sa glfwGetRequiredInstanceExtensions
