      • glfwVulkanSupported

        public static boolean glfwVulkanSupported()
        Returns whether the Vulkan loader has been found. This check is performed by Init.

        The availability of a Vulkan loader does not by itself guarantee that window surface creation or even device creation is possible. Call GetRequiredInstanceExtensions to check whether the extensions necessary for Vulkan surface creation are available and GetPhysicalDevicePresentationSupport to check whether a queue family of a physical device supports image presentation.

        Possible errors include NOT_INITIALIZED.

        This function may be called from any thread.

        Returns:
        TRUE if Vulkan is available, or FALSE otherwise
        Since:
        version 3.2
      • nglfwGetRequiredInstanceExtensions

        public static long nglfwGetRequiredInstanceExtensions​(long count)
        Parameters:
        count - where to store the number of extensions in the returned array. This is set to zero if an error occurred.
      • glfwGetRequiredInstanceExtensions

        @Nullable
        public static org.lwjgl.PointerBuffer glfwGetRequiredInstanceExtensions()
        Returns an array of names of Vulkan instance extensions required by GLFW for creating Vulkan surfaces for GLFW windows. If successful, the list 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.

        If Vulkan is not available on the machine, this function returns NULL and generates a API_UNAVAILABLE error. Call VulkanSupported to check whether Vulkan is available.

        If Vulkan is available but no set of extensions allowing window surface creation was found, this function returns NULL. You may still use Vulkan for off-screen rendering and compute work.

        Additional extensions may be required by future versions of GLFW. You should check if 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.

        The returned array is allocated and freed by GLFW. You should not free it yourself. It is guaranteed to be valid only until the library is terminated.

        This function may be called from any thread.

        Possible errors include NOT_INITIALIZED and API_UNAVAILABLE.

        Returns:
        an array of ASCII encoded extension names, or NULL if an error occurred
        Since:
        version 3.2
      • nglfwGetInstanceProcAddress

        public static long nglfwGetInstanceProcAddress​(long instance,
                                                       long procname)
        Unsafe version of: GetInstanceProcAddress
      • glfwGetInstanceProcAddress

        public static long glfwGetInstanceProcAddress​(@Nullable
                                                      org.lwjgl.vulkan.VkInstance instance,
                                                      java.nio.ByteBuffer procname)
        
        public static long glfwGetInstanceProcAddress​(@Nullable
                                                      org.lwjgl.vulkan.VkInstance instance,
                                                      java.lang.CharSequence procname)
        
        Returns the address of the specified Vulkan core or extension function for the specified instance. If instance is set to NULL it can return any function exported from the Vulkan loader, including at least the following functions:
        • VK10.vkEnumerateInstanceExtensionProperties(java.nio.ByteBuffer, java.nio.IntBuffer, org.lwjgl.vulkan.VkExtensionProperties.Buffer)
        • VK10.vkEnumerateInstanceLayerProperties(java.nio.IntBuffer, org.lwjgl.vulkan.VkLayerProperties.Buffer)
        • VK10.vkCreateInstance(org.lwjgl.vulkan.VkInstanceCreateInfo, org.lwjgl.vulkan.VkAllocationCallbacks, org.lwjgl.PointerBuffer)
        • VK10.vkGetInstanceProcAddr(org.lwjgl.vulkan.VkInstance, java.nio.ByteBuffer)

        If Vulkan is not available on the machine, this function returns NULL and generates a API_UNAVAILABLE error. Call VulkanSupported to check whether Vulkan is available.

        This function is equivalent to calling VK10.vkGetInstanceProcAddr(org.lwjgl.vulkan.VkInstance, java.nio.ByteBuffer) with a platform-specific query of the Vulkan loader as a fallback.

        Possible errors include NOT_INITIALIZED and API_UNAVAILABLE.

        The returned function pointer is valid until the library is terminated.

        This function may be called from any thread.

        Parameters:
        instance - the Vulkan instance to query, or NULL to retrieve functions related to instance creation
        procname - the ASCII encoded name of the function
        Returns:
        the address of the function, or NULL if an error occurred
        Since:
        version 3.2
      • glfwGetPhysicalDevicePresentationSupport

        public static boolean glfwGetPhysicalDevicePresentationSupport​(org.lwjgl.vulkan.VkInstance instance,
                                                                       org.lwjgl.vulkan.VkPhysicalDevice device,
                                                                       int queuefamily)
        Returns whether the specified queue family of the specified physical device supports presentation to the platform GLFW was built for.

        If Vulkan or the required window surface creation instance extensions are not available on the machine, or if the specified instance was not created with the required extensions, this function returns FALSE and generates a API_UNAVAILABLE error. Call VulkanSupported to check whether Vulkan is available and GetRequiredInstanceExtensions to check what instance extensions are required.

        Possible errors include NOT_INITIALIZED, API_UNAVAILABLE and PLATFORM_ERROR.

        This function may be called from any thread. For synchronization details of Vulkan objects, see the Vulkan specification.

        Parameters:
        instance - the instance that the physical device belongs to
        device - the physical device that the queue family belongs to
        queuefamily - the index of the queue family to query
        Returns:
        TRUE if the queue family supports presentation, or FALSE otherwise

      • nglfwCreateWindowSurface

        public static int nglfwCreateWindowSurface​(long instance,
                                                   long window,
                                                   long allocator,
                                                   long surface)
        Unsafe version of: CreateWindowSurface
      • glfwCreateWindowSurface

        public static int glfwCreateWindowSurface​(org.lwjgl.vulkan.VkInstance instance,
                                                  long window,
                                                  @Nullable
                                                  org.lwjgl.vulkan.VkAllocationCallbacks allocator,
                                                  java.nio.LongBuffer surface)
        Creates a Vulkan surface for the specified window.

        If the Vulkan loader was not found at initialization, this function returns VK10.VK_ERROR_INITIALIZATION_FAILED and generates a API_UNAVAILABLE error. Call VulkanSupported 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 VK10.VK_ERROR_EXTENSION_NOT_PRESENT and generates a API_UNAVAILABLE error. Call GetRequiredInstanceExtensions to check what instance extensions are required.

        The window surface cannot be shared with another API so the window must have been created with the client api hint set to NO_API otherwise it generates a INVALID_VALUE error and returns KHRSurface.VK_ERROR_NATIVE_WINDOW_IN_USE_KHR.

        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 KHRSurface.vkDestroySurfaceKHR(org.lwjgl.vulkan.VkInstance, long, org.lwjgl.vulkan.VkAllocationCallbacks) to destroy the surface.

        Possible errors include NOT_INITIALIZED, API_UNAVAILABLE, PLATFORM_ERROR and INVALID_VALUE.

        If an error occurs before the creation call is made, GLFW returns the Vulkan error code most appropriate for the error. Appropriate use of VulkanSupported and GetRequiredInstanceExtensions should eliminate almost all occurrences of these errors.

        This function may be called from any thread. For synchronization details of Vulkan objects, see the Vulkan specification.

        Parameters:
        instance - the Vulkan instance to create the surface in
        window - the window to create the surface for
        allocator - the allocator to use, or NULL to use the default allocator.
        surface - where to store the handle of the surface. This is set to VK10.VK_NULL_HANDLE if an error occurred.
        Returns:
        VK10.VK_SUCCESS if successful, or a Vulkan error code if an error occurred
