FUNCTION
<<fileno>>---return file descriptor associated with stream
INDEX
fileno
ANSI_SYNOPSIS
#include <stdio.h>
int fileno(FILE *<[fp]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fileno(<[fp]>)
FILE *<[fp]>;
DESCRIPTION
You can use <<fileno>> to return the file descriptor identified by <[fp]>.
RETURNS
<<fileno>> returns a non-negative integer when successful.
If <[fp]> is not an open stream, <<fileno>> returns -1.
PORTABILITY
<<fileno>> is not part of ANSI C.
POSIX requires <<fileno>>.
Supporting OS subroutines required: none.
