/***
*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:
*
*******************************************************************************/
