This is indeed true.  If you have dbm, you are probably running
4BSD; if you are running 4BSD, you are probably running either 4.2BSD
or 4.3BSD.  If the former, you can switch to 4.3BSD; if the latter,
or after switching, see man 3x ndbm.

Incidentally, with old dbm, this works after a fashion:

	dbmclose()
	{
		extern int dirf, pagf;
		extern long dblkno, pblkno;

		(void) close(dirf);
		(void) close(pagf);
		dirf = pagf = -1;
		dblkno = pblkno = -1;
	}

if I got the names right (I am working entirely from memory).
