+<H2>DESCRIPTION</H2><PRE>
+ The <STRONG>deleteln</STRONG> and <STRONG>wdeleteln</STRONG> routines delete the line under
+ the cursor in the window; all lines below the current line
+ are moved up one line. The bottom line of the window is
+ cleared. The cursor position does not change.
+
+ The <STRONG>insdelln</STRONG> and <STRONG>winsdelln</STRONG> routines, for positive <EM>n</EM>,
+ insert <EM>n</EM> lines into the specified window above the current
+ line. The <EM>n</EM> bottom lines are lost. For negative <EM>n</EM>,
+ delete <EM>n</EM> lines (starting with the one under the cursor),
+ and move the remaining lines up. The bottom <EM>n</EM> lines are
+ cleared. The current cursor position remains the same.
+
+ The <STRONG>insertln</STRONG> and <STRONG>insertln</STRONG> routines, insert a blank line
+ above the current line and the bottom line is lost.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG>
+ (SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>")
+ upon successful completion.
+
+
+</PRE>
+<H2>PORTABILITY</H2><PRE>
+ These functions are described in the XSI Curses standard,
+ Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on
+ failure, but specifies no error conditions.
+
+
+</PRE>
+<H2>NOTES</H2><PRE>
+ Note that all but <STRONG>winsdelln</STRONG> may be macros.
+
+ These routines do not require a hardware line delete or
+ insert feature in the terminal. In fact, they won't use
+ hardware line delete/insert unless <STRONG>idlok(...,</STRONG> <STRONG>TRUE)</STRONG> has
+ been set on the current window.
