/******************************************************************************
 * BSTR  {OLEAUT32}
 *
 * NOTES
 *  BSTR is a simple typedef for a wide-character string used as the principle
 *  string type in ole automation. When encapsulated in a Variant type they are
 *  automatically copied and destroyed as the variant is processed.
 *
 *  The low level BSTR Api allows manipulation of these strings and is used by
 *  higher level Api calls to manage the strings transparently to the caller.
 *
 *  Internally the BSTR type is allocated with space for a DWORD byte count before
 *  the string data begins. This is undocumented and non-system code should not
 *  access the count directly. Use SysStringLen() or SysStringByteLen()
 *  instead. Note that the byte count does not include the terminating NUL.
 *
 *  To create a new BSTR, use SysAllocString(), SysAllocStringLen() or
 *  SysAllocStringByteLen(). To change the size of an existing BSTR, use SysReAllocString()
 *  or SysReAllocStringLen(). Finally to destroy a string use SysFreeString().
 *
 *  BSTR's are cached by Ole Automation by default. To override this behaviour
 *  either set the environment variable 'OANOCACHE', or call SetOaNoCache().
 *
 * SEE ALSO
 *  'Inside OLE, second edition' by Kraig Brockshmidt.
