Allocation user data</h1>

<p>You can annotate allocations with your own information, e.g. for debugging purposes. To do that, fill <a class="el" href="struct_vma_allocation_create_info.html#a8259e85c272683434f4abb4ddddffe19" title="Custom general-purpose pointer that will be stored in VmaAllocation, can be read as VmaAllocationInfo...">VmaAllocationCreateInfo::pUserData</a> field when creating an allocation. It's an opaque <code>void*</code> pointer. You can use it e.g. as a pointer, some handle, index, key, ordinal number or any other value that would associate the allocation with your custom metadata.</p>

<p>It may be either dedicated block of <code>VkDeviceMemory</code> or a specific region of a bigger block of this type plus unique offset.</p>
|
||||
<p>There are multiple ways to create such object. You need to fill structure <a class="el" href="struct_vma_allocation_create_info.html">VmaAllocationCreateInfo</a>. For more information see <a class="el" href="choosing_memory_type.html">Choosing memory type</a>.</p>
|
||||
<p>Although the library provides convenience functions that create Vulkan buffer or image, allocate memory for it and bind them together, binding of the allocation to a buffer or an image is out of scope of the allocation itself. Allocation object can exist without buffer/image bound, binding can be done manually by the user, and destruction of it can be done independently of destruction of the allocation.</p>
|
||||
<p>The object also remembers its size and some other information. To retrieve this information, use function <a class="el" href="vk__mem__alloc_8h.html#a86dd08aba8633bfa4ad0df2e76481d8b" title="Returns current information about specified allocation and atomically marks it as used in current fra...">vmaGetAllocationInfo()</a> and inspect returned structure <a class="el" href="struct_vma_allocation_info.html" title="Parameters of VmaAllocation objects, that can be retrieved using function vmaGetAllocationInfo(). ">VmaAllocationInfo</a>.</p>
|
||||
<p>Some kinds allocations can be in lost state. For more information, see <a class="el" href="lost_allocations.html">Lost allocations</a>. </p>

<p>Warning: This function is not 100% correct according to Vulkan specification. Use it at your own risk. That's because Vulkan doesn't guarantee that memory requirements (size and alignment) for a new buffer or image are consistent. They may be different even for subsequent calls with the same parameters. It really does happen on some platforms, especially with images.</p>
|
||||
<p>Warning: This function may be time-consuming, so you shouldn't call it too often (like every frame or after every resource creation/destruction). You can call it on special occasions (like when reloading a game level or when you just destroyed a lot of objects). </p>

Although the library provides convenience functions that create Vulkan buffer or image,
|
||||
allocate memory for it and bind them together,
|
||||
binding of the allocation to a buffer or an image is out of scope of the allocation itself.
|
||||
Allocation object can exist without buffer/image bound,
|
||||
binding can be done manually by the user, and destruction of it can be done
|
||||
independently of destruction of the allocation.
|
||||
|
||||
The object also remembers its size and some other information.
|
||||
To retrieve this information, use function vmaGetAllocationInfo() and inspect
|
||||
returned structure VmaAllocationInfo.
|
||||
|
||||
Some kinds allocations can be in lost state.
