It may improve performance on some GPUs.</p>

<p>This function works by moving allocations to different places (different <code>VkDeviceMemory</code> objects and/or different offsets) in order to optimize memory usage. Only allocations that are in pAllocations array can be moved. All other allocations are considered nonmovable in this call. Basic rules:</p>
|
|
<ul>
|
|
<li>Only allocations made in memory types that have <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code> flag can be compacted. You may pass other allocations but it makes no sense - these will never be moved.</li>
|
|
<li>You may pass allocations made with <code>VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT</code> but it makes no sense - they will never be moved.</li>
|
|
<li>Both allocations made with or without <code>VMA_ALLOCATION_CREATE_MAPPED_BIT</code> flag can be compacted. If not persistently mapped, memory will be mapped temporarily inside this function if needed.</li>
|
|
<li>You must not pass same <code>VmaAllocation</code> object multiple times in pAllocations array.</li>
|
|
</ul>
|
|
<p>The function also frees empty <code>VkDeviceMemory</code> blocks.</p>
|
|
<p>After allocation has been moved, its <a class="el" href="struct_vma_allocation_info.html#ae0bfb7dfdf79a76ffefc9a94677a2f67" title="Handle to Vulkan memory object. ">VmaAllocationInfo::deviceMemory</a> and/or <a class="el" href="struct_vma_allocation_info.html#a4a3c732388dbdc7a23f9365b00825268" title="Offset into deviceMemory object to the beginning of this allocation, in bytes.

">vmaGetAllocationInfo()</a> if you need them.</p>
|
|
<p>If an allocation has been moved, data in memory is copied to new place automatically, but if it was bound to a buffer or an image, you must destroy that object yourself, create new one and bind it to the new memory pointed by the allocation. You must use <code>vkDestroyBuffer()</code>, <code>vkDestroyImage()</code>, <code>vkCreateBuffer()</code>, <code>vkCreateImage()</code> for that purpose and NOT <a class="el" href="vk__mem__alloc_8h.html#a0d9f4e4ba5bf9aab1f1c746387753d77" title="Destroys Vulkan buffer and frees allocated memory.

This function is not correct according to Vulkan specification. Use it at your own risk. That's becuase 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>This function may be time-consuming, so you shouldn't call it too often (like every frame or after every resource creation/destruction), but rater you can call it on special occasions (like when reloading a game level, when you just destroyed a lot of objects). </p>

<p>Maps memory represented by given allocation and returns pointer to it. </p>

<p>Maps memory represented by given allocation to make it accessible to CPU code. When succeeded, <code>*ppData</code> contains pointer to first byte of this memory. If the allocation is part of bigger <code>VkDeviceMemory</code> block, the pointer is correctly offseted to the beginning of region assigned to this particular allocation.</p>
|
|
<p>Mapping is internally reference-counted and synchronized, so despite raw Vulkan function <code>vkMapMemory()</code> cannot be used to map same block of <code>VkDeviceMemory</code> multiple times simultaneously, it is safe to call this function on allocations assigned to the same memory block. Actual Vulkan memory will be mapped on first mapping and unmapped on last unmapping.</p>
|

<p>It is also safe to call this function on allocation created with <code>VMA_ALLOCATION_CREATE_MAPPED_BIT</code> flag. Its memory stays mapped all the time.

<p>Sets pUserData in given allocation to new value. </p>
|
|
<p>If the allocation was created with VMA_ALLOCATION_CREATE_USER_DATA_COPY_STRING_BIT, pUserData must be either null, or pointer to a null-terminated string. The function makes local copy of the string and sets it as allocation's pUserData. String passed as pUserData doesn't need to be valid for whole lifetime of the allocation - you can free it after this call. String previously pointed by allocation's pUserData is freed from memory.</p>
|
|
<p>If the flag was not used, the value of pointer pUserData is just copied to allocation's pUserData. It is opaque, so you can use it however you want - e.g. as a pointer, ordinal number or some handle to you own data. </p>
