FERROR(3S)              GENIX Programmer's Manual              FERROR(3S)



      NAME
           feof, ferror, clearerr, fileno - stream status inquiries

      SYNOPSIS
           #include <stdio.h>

           feof(stream)
           FILE *stream;

           ferror(stream)
           FILE *stream

           clearerr(stream)
           FILE *stream

           fileno(stream)
           FILE *stream;

      DESCRIPTION
           Feof returns non-zero when end of file is read on  the  named  input
           stream, otherwise zero.

           Ferror returns non-zero when an error has occurred reading or  writ-
           ing  the  named stream, otherwise zero.  Unless cleared by clearerr,
           the error indication lasts until the stream is closed.

           Clrerr resets the error indication on the named stream.

           Fileno returns the  integer  file  descriptor  associated  with  the
           stream, see open(2).

           These functions are implemented as  macros;  they  cannot  be  rede-
           clared.
