function determines the current
orientation of \fIstream\fP.
It returns a value > 0 if \fIstream\fP is
-wide-character oriented, i.e. if wide-character I/O is permitted but char
+wide-character oriented, that is, if wide-character I/O is permitted but char
I/O is disallowed.
It returns a value < 0 if \fIstream\fP is byte oriented,
i.e. if char I/O is permitted but wide-character I/O is disallowed.
