<p>This function is called "get" not "calculate" because it is very fast, suitable to be called every frame or every allocation. For more detailed statistics use <a class="el" href="group__group__stats.html#ga36f3484de7aa6cd6edc4de9edfa0ff59" title="Retrieves statistics from current state of the Allocator.">vmaCalculateStatistics()</a>.</p>
<p>Note that when using allocator from multiple threads, returned information may immediately become outdated. </p>
