.SH DESCRIPTION
.sp
.LP
The \fBnl()\fR function enables the handling of newlines.  The \fBnl()\fR
function converts newline into carriage return and line feed  on output and
converts carriage return into newline on input.  \fBnonl()\fR disables the
handling of newlines.
.sp
.LP
The handling of newlines is initially enabled.  Disabling the handling of
newlines results in faster cursor motion since  X/Open Curses can use the
line-feed capability more efficiently.
.SH RETURN VALUES
.sp
.LP
On success, these functions return \fBOK\fR. Otherwise, they return \fBERR\fR.
.SH ERRORS
