     FERROR(S)                XENIX System V                 FERROR(S)



     Name
          ferror, feof, clearerr, fileno - Determines stream status.

     Syntax
          #include <stdio.h>

          int feof (stream)
          FILE *stream;

          int ferror (stream)
          FILE *stream

          clearerr (stream)
          FILE *stream

          int fileno(stream)
          FILE *stream;

     Description
          feof returns nonzero when end-of-file is read on the named
          input stream, otherwise zero.

          ferror returns nonzero 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 indication on the named stream.

          fileno returns the integer file descriptor associated with
          the stream, see open(S).

          feof, ferror, and fileno are implemented as macros; they
          cannot be redeclared.
