setlinebuf
==========

Syntax
------

     #include <stdio.h>
     
     void setlinebuf(FILE *file);

Description
-----------

This function modifies the buffering characteristics of FILE.  First,
if the file already has a buffer, it is freed.  If there was any
pending data in it, it is lost, so this function should only be used
immediately after a call to `fopen'.

Next, a buffer is allocated and the file is set to line buffering.

setbuf:.  setlinebuf:.  setvbuf:.         

Return Value
------------

None.

Example
-------

     setlinebuf(stderr);
