       Interfaces documented on this reference page conform to industry	 stan‐
       dards as follows:

       deleteln,    wdeleteln,	  insdelln,    winsdelln,    insertln,	  win‐
       sertln:	XCURSES4.2

       Refer to the standards(5) reference page	 for  more  information	 about
       industry standards and associated tags.

       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
	      lines up

	      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.

       Functions: curses(3)

       Others: standards(5)
