    Extension#
    
+
    在创建 VkInstance 时需要通过 VkInstanceCreateInfo::enabledExtensionCount 和 VkInstanceCreateInfo::ppEnabledExtensionNames 来配置实例要开启的 扩展 （ Extension ）。
    
+
    在 Vulkan 中有两类扩展：
    
+
      
+
    • Instance 扩展 与使用哪一个 GPU 设备无关，与 Vulkan 环境有关。 VkInstanceCreateInfo 中的 enabledExtensionCount 和 ppEnabledExtensionNames 就是用于配置此类 Instance 扩展 。
      • 
+
    • Device 扩展 与使用哪一个 GPU 设备有关。不同厂家的 GPU 设备会支持不同的设备扩展。这将会在之后的章节展开。
      • 
+
    
+
    VkInstance 支持的扩展可以通过 vkEnumerateInstanceExtensionProperties(...) 函数获取：
    
+
    
+
    vkEnumerateInstanceExtensionProperties#
    
+
    // 由 VK_VERSION_1_0 提供
+VkResult vkEnumerateInstanceExtensionProperties(
+    const char*                                 pLayerName,
+    uint32_t*                                   pPropertyCount,
+    VkExtensionProperties*                      pProperties);
+
    
+
    
+
      
+
    • pLayerName 要么为 空 要么为 层 的名称。
      • 
+
    • pPropertyCount 用于指定 pProperties 成员的数组长度。
      • 
+
    • pProperties 如果为 nullptr 则将会将实例支持的 扩展 数写入 pPropertyCount 中。否则会将查询到的元素写入 pProperties 。
      • 
+
    
+
    如果 pLayerName 为有效的 层 名， 该函数将会返回该层内部使用的 扩展 。如果开启了该 层 ，则其内部使用的 扩展 将自动开启。
    
+
    要想获取全部的扩展，该函数的调用与 vkEnumerateInstanceLayerProperties(...) 类似，调用两遍，第一遍 pProperties 为 nullptr ，第二遍为有效值即可：
    
+
    uint32_t extension_property_count = 0;
+vkEnumerateInstanceExtensionProperties(&extension_property_count, nullptr);
+
+std::vector<VkExtensionProperties> extension_properties(extension_property_count);
+vkEnumerateInstanceExtensionProperties(&extension_property_count, extension_properties.data());
+
    
+
    
+
    其中 VkExtensionProperties 定义如下：
    
+
    
+
    
+
    VkExtensionProperties#
    
+
    // 由 VK_VERSION_1_0 提供
+typedef struct VkExtensionProperties {
+    char        extensionName[VK_MAX_EXTENSION_NAME_SIZE];
+    uint32_t    specVersion;
+} VkExtensionProperties;
+
    
+
    
+
      
+
    • extensionName 为扩展名称。
      • 
+
    • specVersion 为扩展该扩展的版本。
      • 
+
    
+
    
+
    有一些扩展我们需要重点关注一下
    
+
      
+
    • VK_KHR_surface 代表窗口通用平面扩展。
      • 
+
    • 
+
      VK_{vender}_{platform}_surface 代表各个平台各自的窗口平面（各自平台适配到通用平面）。其中：
        
+
      • vender 表示该扩展的供应商（或维护方），有的没有提供该供应商字段（取决于扩展开发商）。比如 KHR 表示 Khronos 组织提供维护的该扩展。
        • 
+
      • platform 表示扩展对应的平台。
        • 
+
      
+
      
+
      
+
      • 
+
    
+
    
+
    比如
    
+
      
+
    • VK_KHR_win32_surface 为  Windows 平台，供应商为 Khronos 。
      • 
+
    • VK_OHOS_surface 为 OpenHarmony 平台，供应商为 华为 。
      • 
+
    • VK_KHR_android_surface 为 Android 平台，供应商为 Khronos 。
      • 
+
    • VK_KHR_[wayland/xcb/xlib]_surface 为 Linux 平台（其中 [wayland/xcb/xlib] 表示三者其一），供应商为 Khronos 。
      • 
+
    
+
    
+
    这些扩展在窗口中显示渲染结果非常重要，对于具体如何使用，将会在之后的章节展开。
