Convert C structure to delphi
<p>I need to convert the structure below to delphi. I am in doubt about what this ":4" value means in the "reserved" and "version" members. It looks like it interferes in the size of the structure! Anyone with any tips?</p>

<pre><code>typedef struct _FSRTL_COMMON_FCB_HEADER {
  CSHORT        NodeTypeCode;
  CSHORT        NodeByteSize;
  UCHAR         Flags;
  UCHAR         IsFastIoPossible;
  UCHAR         Flags2;
  UCHAR         Reserved  :4;
  UCHAR         Version  :4;
  PERESOURCE    Resource;
  ...
</code></pre>
