curs_in_wch(3X) Library calls curs_in_wch(3X) NAME in_wch, mvin_wch, mvwin_wch, win_wch - get a curses complex character from a window SYNOPSIS #include <curses.h> int in_wch(cchar_t *wch); int win_wch(WINDOW *win, cchar_t *wch); int mvin_wch(int y, int x, cchar_t *wch); int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wch); DESCRIPTION These functions extract the complex character and rendition from the current position in the named window into the cchar_t object referenced by wch. RETURN VALUE No errors are defined in X/Open Curses. This implementation checks for null pointers, returns ERR in that case. Also, the mv routines check for error moving the cursor, returning ERR in that case. Otherwise they return OK. Functions prefixed with "mv" first perform cursor movement and fail if the position (y, x) is outside the window boundaries. NOTES Note that all of these routines may be macros. PORTABILITY These functions are described in X/Open Curses, Issue 4. SEE ALSO curs_inch(3X) describes comparable functions of the ncurses library in its non-wide-character configuration. curses(3X), curs_inwstr(3X) ncurses 6.5 2024-04-20 curs_in_wch(3X)
