# DESCRIPTION

These functions add character strings to `stdscr` or to the specified window.

The `addstr`() function will add the characters passed in string to `stdscr` starting at the current cursor position. Any background attributes currently set on `stdscr` will be applied to the added character. The `waddstr`() function does the same as `addstr`() but adds the string to the window specified by `win`().

The `addnstr`() function will add the contents of string to `stdscr` but will limit the number of characters added to be, at most, len. If len is -1 then addnstr will add the number of characters contained in the null terminated string string. Any background attributes currently set on `stdscr` will be applied to the added character. The `waddnstr`() function does the same as addnstr but adds the string to the window specified by win.

The functions `mvaddstr`(), `mwaddnstr`(), `mvwaddstr`() and `mvwaddnstr`() are the same as the functions `addstr`(), `waddstr`(), `waddstr`() and `waddnstr`(), respectively, excepting that `wmove`() is called to move the cursor to the position specified by y, x before the string is added to the window.

# RETURN VALUES

Functions returning pointers will return `NULL` if an error is detected. The functions that return an int will return one of the following values:

`OK`
  The function completed successfully.
`ERR`
  An error occurred in the function.
