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>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. X/Open defines no error conditions. In this implementa- tion, if the window parameter is null, an error is returned.</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.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> <STRONG><A HREF="curs_deleteln.3x.html">curs_deleteln(3x)</A></STRONG></PRE><HR><ADDRESS>Man(1) output converted with<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a></ADDRESS></BODY></HTML>⌨️ 快捷键说明
