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




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

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