The directory must be empty. </p> <p> It is an error to attempt to remove the . or .. names in a directory, or to apply rmdir to a filesystem object that is not a directory. </p> <h3>Requirements</h3> <p> <tt>rmdir</tt> uses the following system calls: <ul> <li> <A HREF=../syscall/rmdir.html>rmdir</A> <li> <A HREF=../syscall/write.html>write</A> <li> <A HREF=../syscall/_exit.html>_exit</A> </ul> </p> <p> As the rmdir system call is generally not part of the basic system calls assignment, <tt>rmdir</tt> will usually still not function after the basic system calls assignment is complete. This call is typically part of a later assignment, usually the file system assignment. You may also need to implement subdirectories in the file system. Consult your course materials for specific information. </p> <h3>Restrictions</h3> <p> <A HREF=../dev/emu.html>emufs</A> does not support <tt>rmdir</tt>. (This is intentional.) </p> <h3>See Also</h3> <p> <A HREF=mkdir.html>mkdir</A>, <A HREF=rm.html>rm</A> </p> </body> </html>
