curs_insch(3CURSES)

Name

curs_insch, insch, winsch, mvinsch, mvwinsch - insert a character before the character under the cursor in a curses window

Synopsis

cc [ flag ... ] file... –lcurses [ library ... ]
#include <curses.h>

int insch(chtype ch);
int winsch(WINDOW *win, chtype ch);
int mvinsch(int y, int x, chtype ch);
int mvwinsch(WINDOW *win, int y, int x, chtype ch);

Description

With these routines, the character ch is inserted before the character under the cursor. All characters to the right of the cursor are moved one space to the right, with the possibility of the rightmost character on the line being lost. The cursor position does not change (after moving to y, x, if specified). (This does not imply use of the hardware insert character feature.)

Return Values

All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.

Note that insch(), mvinsch(), and mvwinsch() may be macros.
