CURSES_INSERTLN(3) | Library Functions Manual | CURSES_INSERTLN(3)

# NAME

`curses_insertln`, `insertln`, `winsertln` —
curses insert single line routines

# LIBRARY

Curses Library (libcurses, -lcurses)

# SYNOPSIS

`#include <curses.h>`

int
`insertln`(void);

int
`winsertln`(WINDOW *win);

# DESCRIPTION

These functions insert a single line on `stdscr` or on the specified window.

The `insertln`() function inserts a blank line before the current line on `stdscr`. The current line and all lines below are moved down one line away from the cursor and the bottom line of the window is lost.

The `winsertln`() function is the same as the `insertln`() function, excepting that the line is inserted on the window win.

If a scrolling region has been set with the `setscrreg`() or `wsetscrreg`() functions and the current cursor position is inside the scrolling region, then only the lines from the current line to the bottom of the scrolling region are moved down and the bottom line of the scrolling region lost.

The functions `insertln`() and `winsertln`(win) are equivalent to `insdelln`(1) and `winsdelln`(win, 1), respectively.

# RETURN VALUES

Functions returning pointers will return `NULL` if an error is detected. The functions that return an int will return one of the following values:

`OK`
  The function completed successfully.
`ERR`
  An error occurred in the function.
