curs_insch(S)

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

Syntax

cc ... -lcurses

#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

These routines insert the character ch 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 on failure and an integer value other than ERR on successful completion.

Warning

The header file curses.h automatically includes the header files stdio.h and unctrl.h.

The following can be macros: insch(S), mvinsch(S), and mvwinsch(S).
