 *			Modification History				*
 *									*
 *	David L Ballenger, 25-Jun-1985					*
 * 002	Call setvbuf() to set up the buffering, so that all the buffer	*
 *	handling info can be located in one place.			*
 *									*
 *	Also move setlinebuf to a separate file.			*
 *									*
 *	David L Ballenger, 13-Mar-1985					*
 * 0001	Define setbuffer() and setlinebuf() as returning void.  Since	*
 *	they don't return values.   This brings them into line with	*
 *	setbuf().							*
 *									*
 *	Based on:  setbuffer.c	4.2 (Berkeley) 2/27/83			*
