NAME
ferror, feof, clearerr, fileno - stream status inquiries
SYNOPSIS
#include <stdio.h>
int feof(FILE *stream)
int ferror(FILE *stream)
int clearerr(FILE *stream)
int fileno(FILE *stream)
DESCRIPTION
Feof returns non-zero when end of file is read on the named
input stream, otherwise zero. Unless cleared by clearerr,
the end-of-file indication lasts until the stream is closed.
Ferror returns non-zero when an error has occurred reading
or writing the named stream, otherwise zero. Unless cleared
by clearerr, the error indication lasts until the stream is
closed.
Clearerr resets the error and end-of-file indicators on the
named stream.
Fileno returns the integer file descriptor associated with
the stream, see open(2).
Currently all of these functions are implemented as macros;
they cannot be redeclared.
