How do I swap the buffers when using a Win32 window with Vulkan?
$begingroup$
I was recently told here how to manage the integration between Vulkan and Win32.
I am writing a windowing library like "GLFW", that is only going to support Vulkan; I have now come to the point where I need to implement SwapBuffers(Window) type of function; I have tried to reverse engineer Glfw's glfwSwapBuffers(GLFWWindow*) function to see how they implemented it in their framework, but I wasn't able to understand it fully.
How do I "swap the buffers" in a Win32 window?
P.S: The library is written in C

Then stop doing that. You need that function in OpenGL because the windowing code is explicitly not part of OpenGL, so to write cross-platform GL code, you need an encapsulation layer.
That is not the case for Vulkan. While you still need a layer to create the window, handling the display, swap-chain images, and so forth is all part of the Vulkan API. The user's code should have complete and total control over this stuff; your abstraction layer need not be involved.
Indeed, since Vulkan has no concept of a "default framebuffer", there's no way for you to abstract away presentable images without user support. Just do what GLFW3 does in its Vulkan support: provide a cross-platform way for the user to create a Vulkan surface.
