#include <stdio.h>

FILE *freopen(const char *filename, const char *mode, FILE *file);

@subheading Description

This function closes @var{file} if it was open, then opens a new
file like @code{fopen(filename, mode)} but it reuses @var{file}.

This is useful to, for example, associate @code{stdout} with a new file.

The new file, or @code{NULL} on error.

freopen("/tmp/stdout.dat", "wb", stdout);
