NAME

       ins_wch, mvins_wch, mvwins_wch, wins_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 the pointer is NULL.

       Functions prefixed with “mv” first perform cursor movement using wmove  and  fail  if  the
       position (y, x) is outside the window.

NOTES

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

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

PORTABILITY

       X/Open Curses, Issue 4, describes these functions.

       SVr4 describes successful return values only as “an integer value other than ERR”.

HISTORY

       SVr4  (1989)  implemented  these  functions under the names inswch, winswch, mvinswch, and
       mvwinswch.

SEE ALSO

       insch(3NCURSES)  describes  comparable  functions   in   the   non-wide-character   curses
       configuration.
