addchstr()
The addchstr() functions place a formatted string of text at the cursor s position. The string of formatted text is not a char array, but an array of NCurses chtype characters, which includes both the character and its formatting information.
Man Page Formats
int int int int int int int int addchstr(const chtype *chstr); addchnstr(const chtype *chstr, int n); waddchstr(WINDOW *win, const chtype *chstr); waddchnstr(WINDOW *win, const chtype *chstr, int n); mvaddchstr(int y, int x, const chtype *chstr); mvaddchnstr(int y, int x, const chtype *chstr, int n); mvwaddchstr(WINDOW *win, int y, int x, const chtype *chstr); mvwaddchnstr(WINDOW *win, int y, int x, const chtype *chstr, int n);
Format Reference
chstr is an array of formatted text to be displayed on the screen. The array is composed of chtype characters, which are not char but long int values. (The chtype character consists of a character plus attribute information.) n is used only in the addchnstr() functions. It is an int value, a variable or constant, that represents the maximum number of characters to write to the screen. When n is less than the string s length, then only n characters are displayed. When n is equal to -1, the entire string is displayed. (Also see Notes, below.) When n is greater than the string s length, garbage may be displayed on the screen. Refer to the mv, mvw, and w prefix entries elsewhere in this appendix for information on the win, y, and x arguments.
Return Value
Upon success the addchstr() family of functions return integer constants OK or ERR upon success or failure, respectively. Normally, returns values are not checked with addchstr(); however, if you use the mv- or mvw- prefix versions of the functions, then be sure to check the return value should the function accidentally try to move the cursor to an off-screen location.

Notes
It helps if you understand this function as add-chstr: add a chtype string to the screen. For displaying a standard character string to the screen, use addstr() instead. Unlike other output functions, text displayed by addchstr() does not wrap from one line to another. Any excess text displayed beyond the last column in the window just doesn t appear. addchstr() does not interpret the control characters \t, \n, or \b, nor will it display control characters prefixed with a ^, as other NCurses output functions do. Placing chtype characters on the screen with the addchstr() function is faster than using the addstr() function. The chtype array is terminated with a \0 value, just as char arrays, or strings, are terminated. Try not to use values of n larger than the string. Doing so results in random data being displayed.
Examples
addchnstr(fline,25);
This statement puts the first 25 characters of the chtype string fline to the screen at the current cursor position.
mvaddchstr(0,xc,title);
