The QVulkanDeviceFunctions class provides cross-platform access to the device level core Vulkan 1.0 API.
默认情况下，Qt 和 Qt 应用程序未链接到任何 Vulkan 库。相反，在运行时动态解析所有函数。每个 QVulkanInstance 提供 QVulkanFunctions 可检索对象凭借 QVulkanInstance::functions (). This does not contain device level functions in order to avoid the potential overhead of an internal dispatching. Instead, functions that rely on a device, or a dispatchable child object of a device, are exposed via QVulkanDeviceFunctions and QVulkanInstance::deviceFunctions (). QVulkanFunctions and QVulkanDeviceFunctions together provides access to the full core Vulkan API, excluding any extensions.
注意： QVulkanDeviceFunctions instances cannot be constructed directly.
典型用法如下：
void Window::render()
{
QVulkanInstance *inst = vulkanInstance();
QVulkanDeviceFunctions *df = inst->deviceFunctions(device);
VkResult err = df->vkAllocateCommandBuffers(device, &cmdBufInfo, &cmdBuf);
...
}
The QVulkanDeviceFunctions object specific to the provided VkDevice is created when QVulkanInstance::deviceFunctions () is first called with the device in question. The object is then cached internally.
要访问额外功能，应用程序可以使用 QVulkanInstance::getInstanceProcAddr () and vkGetDeviceProcAddr(). Applications can also decide to link to a Vulkan library directly, as many implementations export function symbols for the core commands. See vkGetInstanceProcAddr 手册页 了解更多信息。
