68 These functions copy the (null-terminated) array of complex characters
69 <EM>wchstr</EM> into the window image structure starting at the current cursor
70 position. The four functions with <EM>n</EM> as the last argument copy at most
71 <EM>n</EM> elements, but no more than will fit on the line. If <STRONG>n</STRONG>=<STRONG>-1</STRONG> then the
72 whole array is copied, to the maximum number of characters that will
75 The window cursor is <EM>not</EM> advanced. These functions work faster than
76 <STRONG>waddnstr</STRONG>. On the other hand:
78 <STRONG>o</STRONG> they do not perform checking (such as for the newline, backspace,
79 or carriage return characters),
81 <STRONG>o</STRONG> they do not advance the current cursor position,
83 <STRONG>o</STRONG> they do not expand other control characters to ^-escapes, and
85 <STRONG>o</STRONG> they truncate the string if it crosses the right margin, rather
86 than wrapping it around to the new line.
88 These functions end successfully on encountering a null <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>, or
89 when they have filled the current line. If a complex character cannot
90 completely fit at the end of the current line, the remaining columns
91 are filled with the background character and rendition.
94 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
95 All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
97 X/Open does not define any error conditions. This implementation re-
98 turns an error if the window pointer is null.
100 Functions with a "mv" prefix first perform a cursor movement using
101 <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
102 the window pointer is null.
