If a NULL window is specified, (chtype)ERR is returned. The in_wch() functions are the wide-character versions; instead of returning a chtype, they store a cchar_t at the address specified by wcval, and return OK or ERR. (No value is stored when ERR is returned.) Note that in PDCurses, chtype and cchar_t are the same.
