IMHO, this is one of *the* strong points of Nut/OS. It enables you to create device
drivers that you can access using standard functions like fprintf,fgets, etc.
In most compiler/developer distributions you can only use stdio functions on files.
If you want to use the supplied functions to control your devices you run into all
sorts of problems, which, in Nut/OS, you don't have.

fopen(UROM:NameOfFile, "r");
