@node setlinebuf, stdio
@subheading Syntax

@example
#include <stdio.h>

void setlinebuf(FILE *file);
@end example

@subheading Description

This function modifies the buffering characteristics of @var{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 @code{fopen}.

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

@xref{setbuf}.
@xref{setlinebuf}.
@xref{setvbuf}.

@subheading Return Value

None.

@subheading Example

@example
setlinebuf(stderr);
@end example
