SETVBUF - set buffering for stream.

(ANSI Standard)

Usage:

#include <stdio.h>
stat = setvbuf(f,b,type,size);

Where:

FILE *f;
 
char *b;
 
int type;
 
size_t size;
 
int stat;
 

Description:

"setvbuf" is included for compatibility with the ANSI standard. In this version of C "setvbuf" does nothing, because the machine already buffers its I/O. The value returned is always non-zero, indicating "failure". Since the library does not use the buffer that "b" points to, there is no reason for the program to retain it; it can be freed.
