#include <curses.h>int in_wchstr(cchar_t *wchstr);int in_wchnstr(cchar_t *wchstr, int n);int win_wchstr(WINDOW *win, cchar_t *wchstr);int win_wchnstr(WINDOW *win, cchar_t *wchstr, int n);int mvin_wchstr(int y, int x, cchar_t *wchstr);int mvin_wchnstr(int y, int x, cchar_t *wchstr, int n);int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wchstr);int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wchstr, int n);
These functions return an array of complex characters in wchstr,
starting at the current cursor position in the named window.
Attributes (rendition) are stored with the characters.
The in_wchnstr, mvin_wchnstr, mvwin_wchnstr and win_wchnstr fill
the array with at most ncchar_t elements.
Note that all routines except win_wchnstr may be macros.
Reading a line that overflows the array pointed to by wchstr with
in_wchstr, mvin_wchstr, mvwin_wchstr or win_wchstr causes
undefined results. Therefore, the use of in_wchnstr,
mvin_wchnstr, mvwin_wchnstr, or win_wchnstr is recommended.
Upon successful completion, these functions return OK.
Otherwise, they return ERR.
Functions with a “mv” prefix first perform a cursor movement
using wmove, and return an error if the position is outside the
window, or if the window pointer is null.
