Wipe out a file using Windows API. No traces, no recover.

Completely destroy a file with no chance of recovery or trace. Use of CreateFile, FILE_FLAG_NO_BUFFERING (Open the file with no intermediate buffering or caching) FILE_FLAG_WRITE_THROUGH (Write through any intermediate cache and go directly to disk) and also FlushFileBuffers function to ensure that file buffers will be flushed! A must test and see.
