#include <curses.h> int insdelln(int n); int winsdelln(WINDOW *win, int n);
The insdelln() and winsdelln() functions perform the following actions:
- If n is positive, these functions insert n lines into the current or specified window before the current line. The n last lines are no longer displayed.
- If n is negative, these functions delete n lines from the current or specified window starting with the current line, and move the remaining lines toward the cursor. The last n lines are cleared.
The current cursor position remains the same.
Upon successful completion, these functions return OK. Otherwise, they return ERR.
No errors are defined.
