FERROR(3)		   Linux Programmer's Manual		     FERROR(3)

       clearerr, feof, ferror, fileno - check and reset stream status

       #include <stdio.h>

       void clearerr(FILE *stream);

       int feof(FILE *stream);

       int ferror(FILE *stream);

       int fileno(FILE *stream);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fileno(): _POSIX_C_SOURCE >= 1 || _XOPEN_SOURCE || _POSIX_SOURCE

       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 nonzero if it is set.  The end-of-file
       indicator can be cleared only by the function clearerr().

       The function ferror() tests the error indicator for the stream  pointed
       to  by stream, returning nonzero if it is set.  The error indicator can
       be reset only by the clearerr() function.

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

       For nonlocking counterparts, see unlocked_stdio(3).

       These  functions	 should	 not fail and do not set the external variable
       errno.  (However, in case fileno() detects that its argument is	not  a
       valid stream, it must return -1 and set errno to EBADF.)

   Multithreading (see pthreads(7))
       The  clearerr(),	 feof(),  ferror(), and fileno() functions are thread-

       The functions clearerr(), feof(), and ferror() conform to C89 and C99.
