These functions copy the (null-terminated) array of complex
characters wchstr into the window image structure starting at the
current cursor position. The four functions with n as the last
argument 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 functions work faster 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 line.
These functions 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 return the integer ERR upon failure and OK on success.
X/Open does not define any error conditions. This implementation
returns an error if the window pointer is null.
Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window, or
if the window pointer is null.
