+*setbuf.c - give new file buffer
+*
+*	Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	defines setbuf() - given a buffer to a stream or make it unbuffered
+*
+*Revision History:
+*	09-19-83  RN	initial version
+*	09-28-87  JCR	Corrected _iob2 indexing (now uses _iob_index() macro).
+*	11-02-87  JCR	Re-wrote to use setvbuf()
+*	12-11-87  JCR	Added "_LOAD_DS" to declaration
+*	05-27-88  PHG	Merged DLL and normal versions
+*	02-15-90  GJF	Fixed copyright and indents
+*	03-19-90  GJF	Replaced _LOAD_DS with _CALLTYPE1 and added #include
+*			<cruntime.h>.
+*	07-23-90  SBM	Replaced <assertm.h> by <assert.h>
+*	10-03-90  GJF	New-style function declarator.

+*void setbuf(stream, buffer) - give a buffer to a stream
+*
+*Purpose:
+*	Allow user to assign his/her own buffer to a stream.
+*		if buffer is not NULL, it must be BUFSIZ in length.
+*		if buffer is NULL, stream will be unbuffered.
+*
+*	Since setbuf()'s functionality is a subset of setvbuf(), simply
+*	call the latter routine to do the actual work.
+*
+*Entry:
+*	FILE *stream - stream to be buffered or unbuffered
+*	char *buffer - buffer of size BUFSIZ or NULL
+*
+*Exit:
+*	None.

+*Exceptions:
