Using the Render Pass and creating the framebuffer

Once the Render Pass is created, it is used to create the framebuffer. Ideally, for each swapchain color image, we need a framebuffer associated with it. For example, if we have a double buffer swapchain image, then we need two framebuffers: one for the front buffer and another for the back buffer image.

The framebuffer in Vulkan is created using the vkCreateFrameBuffer() API. Like with other Vulkan APIs, this also has a create info control structure called VkFrameBufferCreateInfo. Refer to the following for more information on its syntax and usage:

VkResult vkCreateFrameBuffer( 
    VkDevice                           device, 
    const VkFramebufferCreateInfo*     pCreateInfo, 
    const VkAllocationCallbacks*       pAllocator, 
    VkFramebuffer*                     pFrameBuffer); 

The following table describes the various fields of the vkCreateFrameBuffer() API:
