     add_wchstr, add_wchnstr, wadd_wchstr, wadd_wchnstr,
     mvadd_wchstr, mvadd_wchnstr, mvwadd_wchstr, mvwadd_wchnstr -
     add an array of complex characters (and attributes) to a
     curses window


     #include <curses.h>

     int add_wchstr(const cchar_t *wchstr);
     int add_wchnstr(const cchar_t *wchstr, int n);
     int wadd_wchstr(WINDOW * win, const cchar_t *wchstr);
     int wadd_wchnstr(WINDOW * win, const cchar_t *wchstr, int n);
     int mvadd_wchstr(int y, int x, const cchar_t *wchstr);
     int mvadd_wchnstr(int y, int x, const cchar_t *wchstr, int n);
     int mvwadd_wchstr(WINDOW *win, int y, int x, const cchar_t *wchstr);
     int mvwadd_wchnstr(WINDOW *win, int y, int x, const cchar_t *wchstr, int n);


     These routines copy the array of complex characters wchstr
     into the window image structure at and after the current
     cursor position. The four routines with n as the last argu-
     ment copy at most n elements, but no more than will fit on
     the line. If n=-1 then the whole array is copied, to the
     maximum number of characters that will fit on the line.

     The window cursor is not advanced. These routines work fas-
     ter than waddnstr. On the other hand, they do not perform
     checking (such as for the newline, backspace, or carriage
     return characters), they do not advance the current cursor
     position, they do not expand other control characters to ^-
     escapes, and they truncate the string if it crosses the
     right margin, rather than wrapping it around to the new

     These routines end successfully on encountering a null
     cchar_t, or when they have filled the current line. If a
     complex character cannot completely fit at the end of the
     current line, the remaining columns are filled with the
     background character and rendition.


     All functions except wadd_wchnstr may be macros.


     All routines return the integer ERR upon failure and OK on


     All these entry points are described in the XSI Curses stan-
     dard, Issue 4.
