.SH DESCRIPTION
When \fImode\fP is zero, the \fBfwide\fP() function determines the current
-orientation of \fIstream\fP. It returns a value > 0 if \fIstream\fP is
+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
-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. It
+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.
+It
returns zero if \fIstream\fP has no orientation yet; in this case the next
I/O operation might change the orientation (to byte oriented if it is a char
I/O operation, or to wide-character oriented if it is a wide character I/O
.PP
When \fImode\fP is non-zero, the \fBfwide\fP() function first attempts to set
\fIstream\fP's orientation (to wide-character oriented if \fImode\fP > 0, or
-to byte oriented if \fImode\fP < 0). It then returns a value denoting the
+to byte oriented if \fImode\fP < 0).
+It then returns a value denoting the
current orientation, as above.
.SH "RETURN VALUE"
The \fBfwide\fP() function returns the stream's orientation, after possibly
-changing it. A return value > 0 means wide-character oriented. A return value
-< 0 means byte oriented. A return value of zero means undecided.
+changing it.
+A return value > 0 means wide-character oriented.
+A return value
+< 0 means byte oriented.
+A return value of zero means undecided.
