To determine the amount of lazily-allocated memory that is currently committed for a memory object, call:
// Provided by VK_VERSION_1_0 void vkGetDeviceMemoryCommitment( VkDevice device, VkDeviceMemory memory, VkDeviceSize* pCommittedMemoryInBytes);
deviceis the logical device that owns the memory.
memoryis the memory object being queried.
pCommittedMemoryInBytesis a pointer to a
VkDeviceSizevalue in which the number of bytes currently committed is returned, on success.
The implementation may update the commitment at any time, and the value returned by this query may be out of date.
The implementation guarantees to allocate any committed memory from the
heapIndex indicated by the memory type that the memory object was
