=====fprintf=====
Syntax:

<code>
    #include <cstdio>
    int fprintf( FILE *stream, const char *format, ... );
</code>
The fprintf() function sends information (the arguments) according to the
specified format to the file indicated by stream. fprintf() works just like
[[printf|printf()]] as far as the format goes. The return value of fprintf() is the number
of characters outputted, or a negative number if an error occurs. An example:

<code>
     char name[] = "Mary";
     FILE *out = fopen( "output.txt", "w" );
     if( out != NULL )
       fprintf( out, "Hello %s\n", name );
</code>
