| |
| |
| </PRE> |
| <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>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 will not |
| use hardware line delete/insert unless <STRONG>idlok(...,</STRONG> <STRONG>TRUE)</STRONG> |
| has been set on the current window. |
