6 add_wchstr, add_wchnstr, wadd_wchstr, wadd_wchnstr, mvadd_wchstr,

23 These functions copy the (null-terminated) array of complex characters
24 wchstr into the window image structure starting at the current cursor
25 position. The four functions with n as the last argument copy at most
26 n elements, but no more than will fit on the line. If n=-1 then the
27 whole array is copied, to the maximum number of characters that will
28 fit on the line.

30 The window cursor is not advanced. These functions work faster than
31 waddnstr. On the other hand:
32
33 · they do not perform checking (such as for the newline, backspace,
34 or carriage return characters),
35
36 · they do not advance the current cursor position,
37
38 · they do not expand other control characters to ^-escapes, and
39
40 · they truncate the string if it crosses the right margin, rather
41 than wrapping it around to the new line.
42
43 These functions end successfully on encountering a null cchar_t, or
44 when they have filled the current line. If a complex character cannot
45 completely fit at the end of the current line, the remaining columns
46 are filled with the background character and rendition.
47
49 All functions return the integer ERR upon failure and OK on success.
50
51 X/Open does not define any error conditions. This implementation re‐
52 turns an error if the window pointer is null.
53
54 Functions with a "mv" prefix first perform a cursor movement using
55 wmove, and return an error if the position is outside the window, or if
56 the window pointer is null.
57
59 All functions except wadd_wchnstr may be macros.
