<h2><a class="anchor" id="custom_memory_allocator"></a>
Custom memory allocator</h2>
<p>You can use custom memory allocator by filling optional member <a class="el" href="struct_vma_allocator_create_info.html#a6e409087e3be55400d0e4ccbe43c608d" title="Custom CPU memory allocation callbacks. ">VmaAllocatorCreateInfo::pAllocationCallbacks</a>. These functions will be passed to Vulkan, as well as used by the library itself to make any CPU-side allocations.</p>
Custom host memory allocator</h2>
<p>If you use custom allocator for CPU memory rather than default operator <code>new</code> and <code>delete</code> from C++, you can make this library using your allocator as well by filling optional member <a class="el" href="struct_vma_allocator_create_info.html#a6e409087e3be55400d0e4ccbe43c608d" title="Custom CPU memory allocation callbacks.

<h2><a class="anchor" id="allocation_callbacks"></a>
Device memory allocation callbacks</h2>
<p>The library makes calls to <code>vkAllocateMemory()</code> and <code>vkFreeMemory()</code> internally. You can setup callbacks to be informed about these calls, e.g. for the purpose of gathering some statistics. To do it, fill optional member <a class="el" href="struct_vma_allocator_create_info.html#af1380969b5e1ea4c3184a877892d260e" title="Informative callbacks for vkAllocateMemory, vkFreeMemory.

<p>If you want to test how your program behaves with limited amount of Vulkan device memory available (without switching your graphics card to one that really has smaller VRAM), you can use a feature of this library intended for this purpose. To do it, fill optional member <a class="el" href="struct_vma_allocator_create_info.html#a31c192aa6cbffa33279f6d9f0c47c44b" title="Either NULL or a pointer to an array of limits on maximum number of bytes that can be allocated out o...">VmaAllocatorCreateInfo::pHeapSizeLimit</a>.</p>

\subsection custom_memory_allocator Custom host memory allocator
You can use custom memory allocator by filling optional member
VmaAllocatorCreateInfo::pAllocationCallbacks. These functions will be passed to
Vulkan, as well as used by the library itself to make any CPU-side allocations.
If you use custom allocator for CPU memory rather than default operator `new`
and `delete` from C++, you can make this library using your allocator as well
by filling optional member VmaAllocatorCreateInfo::pAllocationCallbacks. These
functions will be passed to Vulkan, as well as used by the library itself to
make any CPU-side allocations.
\subsection allocation_callbacks Device memory allocation callbacks
The library makes calls to `vkAllocateMemory()` and `vkFreeMemory()` internally.
You can setup callbacks to be informed about these calls, e.g. for the purpose
of gathering some statistics. To do it, fill optional member
VmaAllocatorCreateInfo::pDeviceMemoryCallbacks.
\subsection heap_memory_limit Device heap memory limit
If you want to test how your program behaves with limited amount of Vulkan device
memory available (without switching your graphics card to one that really has
smaller VRAM), you can use a feature of this library intended for this purpose.
To do it, fill optional member VmaAllocatorCreateInfo::pHeapSizeLimit.

If not NULL, it must be a pointer to an array of
`VkPhysicalDeviceMemoryProperties::memoryHeapCount` elements, defining limit on
maximum number of bytes that can be allocated out of particular Vulkan memory
heap.
Any of the elements may be equal to `VK_WHOLE_SIZE`, which means no limit on that
heap. This is also the default in case of `pHeapSizeLimit` = NULL.
If there is a limit defined for a heap:
- If user tries to allocate more memory from that heap using this allocator,
the allocation fails with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
- If the limit is smaller than heap size reported in `VkMemoryHeap::size`, the
value of this limit will be reported instead when using vmaGetMemoryProperties().
