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
All functions return the integer ERR upon failure and OK on
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.
