       ferror, feof, clearerr, fileno - stream status inquiries

SYNOPSIS

       #include <stdio.h>

       int ferror(FILE *stream);

       int feof(FILE *stream);

       void clearerr(FILE *stream);

       int fileno(FILE *stream);

DESCRIPTION

       The  ferror()  function	returns  a  non-zero  value when an error has previously occurred reading from or writing to the named stream (see
       Intro(3)). It returns 0 otherwise.

       The feof() function returns a non-zero value when EOF has previously been detected reading the named input stream. It returns 0 otherwise.

       The clearerr() function resets the error indicator and EOF indicator to 0 on the named stream.

       The fileno() function returns the integer file descriptor associated with the named stream; see open(2).
