title: How to find GPU memory(video memory) using NVAPI
body: <p>I am using NVAPI, I can get some performance data by calling this function:</p>
  
  <pre><code>NvAPI_GPU_GetDynamicPstatesInfoEx
  </code></pre>
  
  <p>But don't know how to get video memory usage. I find <a href="http://open-hardware-monitor.googlecode.com/svn/trunk/Hardware/Nvidia/NvidiaGPU.cs" rel="nofollow">some c# codes</a> call this function to get it.</p>
  
  <pre><code>NVAPI.NvAPI_GPU_GetMemoryInfo
  </code></pre>
  
  <p>But there is no the same function in NVAPI.</p>
  
  <p>Any idea?</p>
