All of these routines copy chstr 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 works faster than waddnstr() (see curs_addstr(3CURSES)) because they merely copy chstr into the window image structure. On the other hand, care must be taken when using these functions because they do not 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 then wrapping it around to the next line.

All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.

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

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

The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.

Note that all routines except waddchnstr() and waddchstr() may be macros.
