</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></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>winsertln</STRONG> routines insert a blank line above the
current line and the bottom line is lost.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></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.
X/Open defines no error conditions. In this implementation, if the
window parameter is null, an error is returned.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></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><a name="h2-NOTES">NOTES</a></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 will not use hardware line
delete/insert unless <STRONG>idlok(...,</STRONG> <STRONG>TRUE)</STRONG> has been set on the current
window.
