So the file descriptors returned by `open` behave an awful lot like the pair allocated to a pipe or socketpair, which bear a striking resemblence to a socket descriptor, and so on; all can be the target of a `write`, or `read`, or `close`. Of course there are some differences as those are different kinds of objects after all. What does `lseek` mean on a pipe? It doesn't; it's a category error, and POSIX defines it thusly. But in terms of general shape of the interface, the analogy is not bad, though it's not the "filesystem" that does this, but rather, the file-related API. Of course, those _system calls_ don't do formatting of their own (modulo a tty layer that might do, say, line end conversions or things like that). >There is a lot to be said for the terseness of *printf formatting, >particularly with compilers that check the type correctness of the printf >varargs list. I'd say the real winning example is `snprintf`, where one can format directly into a character array. It is difficult to understate the utility this; but if `print` were built into the language, you'd lose it, unless you also had a `sprint` builtin. - Dan C.
