The only way I know how to do that is to read the file into a buffer, then using ios::trunc put your new output into the file, and then the contents of the buffer.
Perhaps someone knows a better way to do this than me...

No, there's no other way.
The only file operations are clear, append, and changing the value of random bytes.
