PARAMETERS    [Toc]    [Back]

       Specifies the input or output stream.

DESCRIPTION    [Toc]    [Back]

       The  ferror()  function  tests whether input/output errors
       have occurred on the specified stream.

NOTES    [Toc]    [Back]

       [Tru64  UNIX]  The  ferror()  function  may  be  a   macro
       (depending  on  the  compile-time  definitions used in the
       source). Consequently, you cannot use this interface where
       a function is necessary; for example, a subroutine pointer
       cannot point to it.

RETURN VALUES    [Toc]    [Back]

       If an I/O error occurred when reading from or  writing  to
       the  stream  specified  by the stream parameter, a nonzero
       value is returned.  Otherwise, a  value  of  0  (zero)  is
       returned.
