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

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

     #include <stdio.h>

     clearerr(FILE *stream);

     feof(FILE *stream);

     ferror(FILE *stream);

     fileno(FILE *stream);

     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 point-
     ed to by stream, returning non-zero if it is set.  The end-of-file indi-
     cator 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 clearerr() function.

     The function fileno() examines the argument stream and returns its inte-
     ger file descriptor.

     These functions should not fail and do not set the external variable

     open(2),  stdio(3)

     The functions clearerr(), feof(), and ferror() conform to ANSI
     X3.159-1989 (``ANSI C''). The function fileno() conforms to IEEE
     Std1003.1-1990 (``POSIX'').
