vkDestroyFramebuffer

To destroy a framebuffer, call:

void vkDestroyFramebuffer(
    VkDevice device,
    VkFramebuffer framebuffer,
    const VkAllocationCallbacks* pAllocator);

device is the logical device that destroys the framebuffer.
framebuffer is the handle of the framebuffer to destroy.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.

All submitted commands that refer to framebuffer must have completed execution

If VkAllocationCallbacks were provided when framebuffer was created, a compatible set of callbacks must be provided here

If no VkAllocationCallbacks were provided when framebuffer was created, pAllocator must be NULL

device must be a valid VkDevice handle

If framebuffer is not VK_NULL_HANDLE, framebuffer must be a valid VkFramebuffer handle

If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

If framebuffer is a valid handle, it must have been created, allocated, or retrieved from device
