     rmdir(const char *path);

DESCRIPTION

     Rmdir() removes a directory file whose name is given by path.  The direc-
     tory must not have any entries other than `.' and `..'.

RETURN VALUES

     A 0 is returned if the remove succeeds; otherwise a -1 is returned and an
     error code is stored in the global location errno.

ERRORS

     The named file is removed unless:

     [ENOTDIR]          A component of the path is not a directory.

     [ENAMETOOLONG]     A component of a pathname exceeded {NAME_MAX} charac-
                        ters, or an entire path name exceeded {PATH_MAX} char-
                        acters.

     [ENOENT]           The named directory does not exist.

     [ELOOP]            Too many symbolic links were encountered in translat-
                        ing the pathname.

     [ENOTEMPTY]        The named directory contains files other than `.' and
                        `..' in it.

     [EACCES]           Search permission is denied for a component of the
                        path prefix.

     [EACCES]           Write permission is denied on the directory containing
                        the link to be removed.

     [EPERM]            The directory containing the directory to be removed
                        is marked sticky, and neither the containing directory
                        nor the directory to be removed are owned by the
                        effective user ID.

     [EBUSY]            The directory to be removed is the mount point for a
                        mounted file system.

     [EIO]              An I/O error occurred while deleting the directory
                        entry or deallocating the inode.

     [EROFS]            The directory entry to be removed resides on a read-
                        only file system.

     [EFAULT]           Path points outside the process's allocated address
                        space.
