    curs_ins_wch(3x)                 Library calls                curs_ins_wch(3x)

## NAME

           ins_wch,  wins_wch,  mvins_wch,  mvwins_wch  -  insert a curses complex
           character in a window

## SYNOPSIS

           #include <curses.h>

           int ins_wch(const cchar_t * wch);
           int wins_wch(WINDOW * win, const cchar_t * wch);
           int mvins_wch(int y, int x, const cchar_t * wch);
           int mvwins_wch(WINDOW * win, int y, int x, const cchar_t * wch);

## DESCRIPTION

           These functions insert the curses complex character wch at  the  cursor
           in  the  specified window win (or stdscr).  The character previously at
           the cursor and any to its  right  move  one  cell  to  the  right;  the
           rightmost  character  on  the  line  is discarded.  The cursor does not
           advance.

## RETURN VALUE

           These functions return OK on success and ERR on failure.

           Functions taking a WINDOW pointer  argument  fail  if  win  is  a  null
           pointer.

           Functions  prefixed with "mv" first perform cursor movement and fail if
           the position (y, x) is outside the window boundaries.

## NOTES

           ins_wch, mvins_wch, and mvwins_wch may be implemented as macros.

           A terminal's insert_character  (ich1)  capability  is  not  necessarily
           employed.

## PORTABILITY

           X/Open Curses Issue 4 describes these functions.  It specifies no error
           conditions for them.

## HISTORY

           X/Open Curses Issue 4 (1995) initially specified these functions.   The
           System V  Interface  Definition  Version 4 of the same year specified a
           function named winswch (and the usual  variants).   This  was  a  later
           addition  to  SVr4.x,  not  appearing  in  the  first  SVr4 (1989).  It
           differed from X/Open's later wins_wch in that it took  an  argument  of
           type chtype instead of cchar_t.

## SEE ALSO

           curs_insch(3x) describes comparable functions in the non-wide-character
           curses configuration.
