/******************************************************************************
* 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.
