       int rmdir(const char *pathname);

       rmdir() deletes a directory, which must be empty.

       On  success,  zero is returned.  On error, -1 is returned, and errno is
       set appropriately.

       EACCES Write access  to  the  directory  containing  pathname  was  not
              allowed,  or  one of the directories in the path prefix of path-
              name did not allow search permission.   (See  also  path_resolu-

       EBUSY  pathname  is currently in use by the system or some process that
              prevents its removal.  On Linux this means pathname is currently
              used  as  a  mount point or is the root directory of the calling

       EFAULT pathname points outside your accessible address space.

       EINVAL pathname has .  as last component.

       ELOOP  Too many symbolic links were encountered in resolving pathname.

              pathname was too long.

       ENOENT A directory component in pathname does not exist or  is  a  dan-
              gling symbolic link.

       ENOMEM Insufficient kernel memory was available.

              pathname,  or  a  component  used as a directory in pathname, is
              not, in fact, a directory.

              pathname contains entries other than . and .. ; or, pathname has
              ..  as its final component.  POSIX.1 also allows EEXIST for this

       EPERM  The directory containing pathname has the sticky  bit  (S_ISVTX)
              set  and  the process's effective user ID is neither the user ID
              of the file to be deleted nor that of the  directory  containing
              it,  and the process is not privileged (Linux: does not have the
              CAP_FOWNER capability).

       EPERM  The filesystem containing pathname does not support the  removal
              of directories.
