+.SH NAME
+clearerr, feof, ferror \- check and reset stream status
+.SH LIBRARY
+Standard C library

+.SH SYNOPSIS

+.SH DESCRIPTION
+The function
+.BR clearerr ()
+clears the end-of-file and error indicators for the stream pointed to by
+.IR stream .
+.P
+The function
+.BR feof ()
+tests the end-of-file indicator for the stream pointed to by
+.IR stream ,
+returning nonzero if it is set.
+The end-of-file indicator can be cleared only by the function
+.BR clearerr ().
+.P
+The function
+.BR ferror ()
+tests the error indicator for the stream pointed to by
+.IR stream ,
+returning nonzero if it is set.
+The error indicator can be reset only by the
+.BR clearerr ()
+function.
+.P
+For nonlocking counterparts, see
+.BR unlocked_stdio (3).
+.SH RETURN VALUE
+The
+.BR feof ()
+function returns nonzero if the end-of-file indicator is set for
+.IR stream ;
+otherwise, it returns zero.
+.P
+The
+.BR ferror ()
+function returns nonzero if the error indicator is set for
+.IR stream ;
+otherwise, it returns zero.
+.SH ERRORS
+These functions should not fail and do not set
+.IR errno .

+.SH NOTES
+POSIX.1-2008 specifies
+.\"https://www.austingroupbugs.net/view.php?id=401
+that these functions shall not change the value of
+.I errno
+if
+.I stream
+is valid.
+.SH CAVEATS
+Normally,
+programs should read the return value of an input function,
+such as
+.BR fgetc (3),
+before using functions of the
+.BR feof (3)
+family.
+Only when the function returned the sentinel value
+.B EOF
+it makes sense to distinguish between the end of a file or an error with
+.BR feof (3)
+or
+.BR ferror (3).
