C Specification
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);
Parameters
-
device
is the logical device that owns the memory. -
memory
is the memory object being queried. -
pCommittedMemoryInBytes
is a pointer to a VkDeviceSize value in which the number of bytes currently committed is returned, on success.
Description
The implementation may update the commitment at any time, and the value returned by this query may be out of date.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
created with.
