NAME
     rmdir -- remove a directory file

SYNOPSIS
     #include <unistd.h>

     int
     rmdir(const char *path);

DESCRIPTION
     Rmdir() removes a directory file whose name is given by path.  The directory 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:

     [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.

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

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

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

     [ELOOP]		Too many symbolic links are encountered in translating the pathname.  This is taken to be indicative of a looping symbolic
			link.

     [ENAMETOOLONG]	A component of a pathname (possibly expanded by a symbolic link) exceeds {NAME_MAX} characters, or an entire path name
			exceeded {PATH_MAX} characters.

     [ENOENT]		The named directory does not exist.

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

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

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

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