For a BSTR allocated with SysAllocStringLen, SysReAllocStringLen, or SysAllocStringByteLen, this function always retrieves the number of bytes specified in the len parameter at allocation time.

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
