clearerr, feof, ferror, fileno - check and reset stream
status
SYNOPSIS
#include <stdio.h>
void clearerr( FILE *stream);
int feof( FILE *stream);
int ferror( FILE *stream);
int fileno( FILE *stream);
DESCRIPTION
The function clearerr clears the end-of-file and error
indicators for the stream pointed to by stream.
The function feof tests the end-of-file indicator for the
stream pointed to by stream, returning non-zero if it is
set. The end-of-file indicator can only be cleared by the
function clearerr.
The function ferror tests the error indicator for the
stream pointed to by stream, returning non-zero if it is
set. The error indicator can only be reset by the clear
err function.
The function fileno examines the argument stream and
returns its integer descriptor.
ERRORS
These functions should not fail and do not set the exter
nal variable errno. (However, in case fileno detects that
its argument is not a valid stream, it must return -1 and
set errno to EBADF.)
CONFORMING TO
The functions clearerr, feof, and ferror conform to
X3.159-1989 (``ANSI C'').
