### Synopsis
|
|
|
|
int deleteln(void);
|
|
int wdeleteln(WINDOW *win);
|
|
int insdelln(int n);
|
|
int winsdelln(WINDOW *win, int n);
|
|
int insertln(void);
|
|
int winsertln(WINDOW *win);
|
|
|
|
int mvdeleteln(int y, int x);
|
|
int mvwdeleteln(WINDOW *win, int y, int x);
|
|
int mvinsertln(int y, int x);
|
|
int mvwinsertln(WINDOW *win, int y, int x);
|
|
|
|
### Description
|
|
|
|
With the deleteln() and wdeleteln() functions, the line under the
|
|
cursor in the window is deleted. 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.
|
|
|
|
With the insertln() and winsertn() functions, a blank line is
|
|
inserted above the current line and the bottom line is lost.
|
|
|
|
mvdeleteln(), mvwdeleteln(), mvinsertln() and mvwinsertln() allow
|
|
moving the cursor and inserting/deleting in one call.
|
|
|
|
### Return Value
|
|
|
|
All functions return OK on success and ERR on error.
|
|
|
|
