+ Name: deleteln
+
+ 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.
