All of these routines copy wchstr, which points to a string of wchar_t characters, directly into the window image structure starting at the current cursor position. The four routines 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 string is copied, to the maximum number that fit on the line.

The position of the window cursor is not advanced. These routines work faster than waddnwstr(3CURSES) because they merely copy wchstr into the window image structure. On the other hand, care must be taken when using these functions because they don't perform any kind of checking (such as for the newline character), they do not advance the current cursor position, and they truncate the string, rather than wrapping it around to the new line.

All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion, unless otherwise noted in the preceding routine descriptions.

See attributes(5) for descriptions of the following attributes:

curses(3CURSES), waddnwstr(3CURSES), attributes(5)

The header file <curses.h> automatically includes the header files <stdio.h>, <unctrl.h> and <widec.h>.

Note that all routines except waddwchnstr() may be macros.

None of these routines can use the color attribute in chtype.
