<H2>DESCRIPTION</H2><PRE>
|
||
|
|
The <B>deleteln</B> and <B>wdeleteln</B> 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 <B>insdelln</B> and <B>winsdelln</B> routines, for positive <I>n</I>,
|
||
|
|
insert <I>n</I> lines into the specified window above the current
|
||
|
|
line. The <I>n</I> bottom lines are lost. For negative <I>n</I>,
|
||
|
|
delete <I>n</I> lines (starting with the one under the cursor),
|
||
|
|
and move the remaining lines up. The bottom <I>n</I> lines are
|
||
|
|
cleared. The current cursor position remains the same.
|
||
|
|
|
||
|
|
The <B>insertln</B> and <B>insertln</B> routines, insert a blank line
|
||
|
|
above the current line and the bottom line is lost.
|
||
|
|
|

|

|
||
|
|
<H2>RETURN VALUE</H2><PRE>
|
||
|
|
All routines return the integer <B>ERR</B> upon failure and an <B>OK</B>
|
||
|
|
(SVr4 specifies only "an integer value other than <B>ERR</B>")
|
||
|
|
upon successful completion.
|
||
|

|
||
|
|
<H2>PORTABILITY</H2><PRE>
|
||
|
|
These functions are described in the XSI Curses standard,
|
||
|
|
Issue 4. The standard specifies that they return <B>ERR</B> on
|
||
|
|
failure, but specifies no error conditions.
|
||
|
|
|
||
|
|
|
||
|
|

|
||
|
|
<H2>NOTES</H2><PRE>
|
||
|
|
Note that all but <B>winsdelln</B> 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 <B>idlok(...,</B> <B>TRUE)</B> has
|
||
|
|
been set on the current window.
