.\} .\} \%ins_wch, \%mvins_wch, \%mvwins_wch, \%wins_wch - insert a curses complex character in a window

#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);

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. 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 and fail if the position ( y , x ) is outside the window boundaries.

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

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

X/Open Curses, Issue 4 describes these functions.

SVr4 describes successful return values only as \*(``an integer value other than ERR\*(''.

SVr4 (1989) implemented these functions under the names inswch , winswch , mvinswch , and mvwinswch . \%curs_insch(3X) describes comparable functions in the non-wide-character curses configuration.
