SYNOPSIS

#include <stdio.h>
void clearerr (FILE *stream);
void clearerr_unlocked (FILE *stream);
int feof (FILE *stream);
int feof_unlocked (FILE *stream);
int ferror (FILE *stream);
int ferror_unlocked (FILE *stream);
int fileno (FILE *stream);
int fileno_unlocked (FILE *stream);

DESCRIPTION

The function clearerr ();
clears the end-of-file and error indicators for the stream pointed to by Fa stream .

The function feof ();
tests the end-of-file indicator for the stream pointed to by Fa 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 Fa stream , returning non-zero if it is set. The error indicator can only be reset by the clearerr ();
function.

The function fileno ();
examines the argument Fa stream and returns its integer descriptor.

The clearerr_unlocked (,);
feof_unlocked (,);
ferror_unlocked (,);
and fileno_unlocked ();
functions are equivalent to clearerr (,);
feof (,);
ferror (,);
and fileno ();
respectively, except that the caller is responsible for locking the stream with flockfile(3) before calling them. These functions may be used to avoid the overhead of locking the stream and to prevent races when multiple threads are operating on the same stream.
