ferror, feof, clearerr, fileno - stream status inquiries
SYNOPSIS
#include <stdio.h>
int feof(FILE *stream);
int ferror(FILE *stream);
void 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 (which is not an ANSI C function) returns the integer file
descriptor associated with the stream, see open(2).
