  53  * BSTR  {OLEAUT32}
  54  *
  55  * NOTES
  56  *  BSTR is a simple typedef for a wide-character string used as the principle
  57  *  string type in ole automation. When encapsulated in a Variant type they are
  58  *  automatically copied and destroyed as the variant is processed.
  59  *
  60  *  The low level BSTR Api allows manipulation of these strings and is used by
  61  *  higher level Api calls to manage the strings transparently to the caller.
  62  *
  63  *  Internally the BSTR type is allocated with space for a DWORD byte count before
  64  *  the string data begins. This is undocumented and non-system code should not
  65  *  access the count directly. Use SysStringLen() or SysStringByteLen()
  66  *  instead. Note that the byte count does not include the terminating NUL.
  67  *
  68  *  To create a new BSTR, use SysAllocString(), SysAllocStringLen() or
  69  *  SysAllocStringByteLen(). To change the size of an existing BSTR, use SysReAllocString()
  70  *  or SysReAllocStringLen(). Finally to destroy a string use SysFreeString().
  71  *
  72  *  BSTR's are cached by Ole Automation by default. To override this behaviour
  73  *  either set the environment variable 'OANOCACHE', or call SetOaNoCache().
  74  *

  76  *  'Inside OLE, second edition' by Kraig Brockshmidt.
