* fstat: sys/stat.h
* lstat: sys/stat.h
* mkdir: sys/stat.h
*
* If this were standard Unix, more prototypes would go in other
* header files as well, as follows:
*
* waitpid: sys/wait.h
* open: fcntl.h or sys/fcntl.h
* reboot: sys/reboot.h
* ioctl: sys/ioctl.h
* remove: stdio.h
* rename: stdio.h
* time: time.h
*
* Also note that the prototypes for open() and mkdir() contain, for
* compatibility with Unix, an extra argument that is not meaningful
* in OS/161. This is the "mode" (file permissions) for a newly created
* object. (With open, if no file is created, this is ignored, and the
* call prototype is gimmicked so it doesn't have to be passed either.)
*
* You should ignore these arguments in the OS/161 kernel unless you're
* implementing security and file permissions.
*
* If you are implementing security and file permissions and using a
* model different from Unix so that you need different arguments to
* these calls, you may make appropriate changes, or define new syscalls
* with different names and take the old ones out, or whatever.
*
* As a general rule of thumb, however, while you can make as many new
* syscalls of your own as you like, you shouldn't change the
* definitions of the ones that are already here. They've been written
* to be pretty much compatible with Unix, and the teaching staff has
* test code that expects them to behave in particular ways.
*
* Of course, if you want to redesign the user/kernel API and make a
* lot of work for yourself, feel free, just contact the teaching
* staff beforehand. :-)
*
* The categories (required/recommended/optional) are guesses - check
* the text of the various assignments for an authoritative list.
