To free a memory object, call:
void vkFreeMemory( VkDevice device, VkDeviceMemory memory, const VkAllocationCallbacks* pAllocator);
deviceis the logical device that owns the memory.
VkDeviceMemoryobject to be freed.
pAllocatorcontrols host memory allocation as described in the Memory Allocation chapter.
Before freeing a memory object, an application must ensure the memory object is no longer in use by the device—for example by command buffers in the pending state. The memory can remain bound to images or buffers at the time the memory object is freed, but any further use of them (on host or device) for anything other than destroying those objects will result in undefined behavior. If there are still any bound images or buffers, the memory may not be immediately released by the implementation, but must be released by the time all bound images and buffers have been destroyed. Once memory is released, it is returned to the heap from which it was allocated.
How memory objects are bound to Images and Buffers is described in detail in the Resource Memory Association section.
If a memory object is mapped at the time it is freed, it is implicitly unmapped.
As described below, host writes are not implicitly flushed when the memory object is unmapped, but the implementation must guarantee that writes that have not been flushed do not affect any other memory.
