Detailed Description

Member Data Documentation

VkDeviceMemory VmaAllocationInfo::deviceMemory

Handle to Vulkan memory object.

Same memory object can be shared by multiple allocations.

It can change after call to vmaDefragment() if this allocation is passed to the function, or if allocation is lost.

If the allocation is lost, it is equal to VK_NULL_HANDLE.

uint32_t VmaAllocationInfo::memoryType

Memory type index that this allocation was allocated from.

It never changes.

VkDeviceSize VmaAllocationInfo::offset

Offset into deviceMemory object to the beginning of this allocation, in bytes. (deviceMemory, offset) pair is unique to this allocation.

It can change after call to vmaDefragment() if this allocation is passed to the function, or if allocation is lost.

void* VmaAllocationInfo::pMappedData

Pointer to the beginning of this allocation as mapped data.

If the allocation hasn't been mapped using vmaMapMemory() and hasn't been created with VMA_ALLOCATION_CREATE_MAPPED_BIT flag, this value is null.

It can change after call to vmaMapMemory(), vmaUnmapMemory(). It can also change after call to vmaDefragment() if this allocation is passed to the function.

void* VmaAllocationInfo::pUserData

Custom general-purpose pointer that was passed as VmaAllocationCreateInfo::pUserData or set using vmaSetAllocationUserData().

It can change after call to vmaSetAllocationUserData() for this allocation.

VkDeviceSize VmaAllocationInfo::size

Size of this allocation, in bytes.

It never changes, unless allocation is lost.
