47 * BSTR {OLEAUT32}
48 *
49 * NOTES
50 * BSTR is a simple typedef for a wide-character string used as the principle
51 * string type in ole automation. When encapsulated in a Variant type they are
52 * automatically copied and destroyed as the variant is processed.
53 *
54 * The low level BSTR Api allows manipulation of these strings and is used by
55 * higher level Api calls to manage the strings transparently to the caller.
56 *
57 * Internally the BSTR type is allocated with space for a DWORD byte count before
58 * the string data begins. This is undocumented and non-system code should not
59 * access the count directly. Use SysStringLen() or SysStringByteLen()
60 * instead. Note that the byte count does not include the terminating NUL.
61 *
62 * To create a new BSTR, use SysAllocString(), SysAllocStringLen() or
63 * SysAllocStringByteLen(). To change the size of an existing BSTR, use SysReAllocString()
64 * or SysReAllocStringLen(). Finally to destroy a string use SysFreeString().
65 *
66 * BSTR's are cached by Ole Automation by default. To override this behaviour
67 * either set the environment variable 'OANOCACHE', or call SetOaNoCache().
68 *
