Yes. Great! Exactly what I was looking for. I guess I need to include
more headers. But where is it descided in the program that the file opened
written to and eventually closed is going to be a binary or text file?
At the POSIX level, there is no such thing as a "binary" or "text" file. To
the OS (and these calls) it's all just bytes of data.
