DESCRIPTION

30       The in_wch() and win_wch() functions retrieve the complex character and
31       its  rendition  located  at  the current cursor position of the  stdscr
32       window and window win, respectively.  The  mvin_wch()  and  mvwin_wch()
33       functions  retrieve  the complex character and its rendition located at
34       the position indicated by the x  (column) and y (row)  parameters  (the
35       former in the stdscr window; the latter in window win).
36
37
38       All  these functions store the retrieved character and its rendition in
39       the  object pointed to by wcval.
40
