The deleteln and wdeleteln routines do the following: Delete the line
under the cursor in the current or specified window Move all lines
below the current line up one line Clear the bottom line of the window
These routines do not change the cursor position. (This does not imply
use of a hardware delete line feature.)
The insdelln and winsdelln routines do the following: For positive n,
insert n lines into the current or specified window above the current
The n bottom lines are lost. For negative n, delete n lines
(starting with the one under the cursor), and move the remaining
The bottom n lines are cleared.
These routines do not change the current cursor position.
The insertln and insertln routines insert a blank line above the cur‐
rent line. The bottom line is lost. (This does not imply use of a hard‐
ware insert line feature.)
The header file <curses.h> automatically includes the header file
Note that all routines except winsdelln may be macros.
All routines return ERR upon failure and OK upon successful completion.
