67 <H2>DESCRIPTION</H2><PRE>
68 The <STRONG>deleteln</STRONG> and <STRONG>wdeleteln</STRONG> routines delete the line under
69 the cursor in the window; all lines below the current line
70 are moved up one line. The bottom line of the window is
71 cleared. The cursor position does not change.
73 The <STRONG>insdelln</STRONG> and <STRONG>winsdelln</STRONG> routines, for positive <EM>n</EM>,
74 insert <EM>n</EM> lines into the specified window above the current
75 line. The <EM>n</EM> bottom lines are lost. For negative <EM>n</EM>,
76 delete <EM>n</EM> lines (starting with the one under the cursor),
77 and move the remaining lines up. The bottom <EM>n</EM> lines are
78 cleared. The current cursor position remains the same.
80 The <STRONG>insertln</STRONG> and <STRONG>winsertln</STRONG> routines insert a blank line
81 above the current line and the bottom line is lost.
85 <H2>RETURN VALUE</H2><PRE>
86 All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG>
87 (SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>")
88 upon successful completion.
90 X/Open defines no error conditions. In this implementa-
91 tion, if the window parameter is null, an error is
96 <H2>PORTABILITY</H2><PRE>
97 These functions are described in the XSI Curses standard,
98 Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on
99 failure, but specifies no error conditions.
104 Note that all but <STRONG>winsdelln</STRONG> may be macros.
106 These routines do not require a hardware line delete or
107 insert feature in the terminal. In fact, they will not
108 use hardware line delete/insert unless <STRONG>idlok(...,</STRONG> <STRONG>TRUE)</STRONG>
109 has been set on the current window.
