NAME
addchstr, addchnstr, waddchstr, waddchnstr, mvaddchstr, mvaddchnstr, mvwaddchstr, mvwaddchnstr - add a string of characters (and attributes) to a curses window SYNOPSIS
#include <curses.h> int addchstr(const chtype *chstr); int addchnstr(const chtype *chstr, int n); int waddchstr(WINDOW *win, const chtype *chstr); int waddchnstr(WINDOW *win, const chtype *chstr, int n); int mvaddchstr(int y, int x, const chtype *chstr); int mvaddchnstr(int y, int x, const chtype *chstr, int n); int mvwaddchstr(WINDOW *win, int y, int x, const chtype *chstr); int mvwaddchnstr(WINDOW *win, int y, int x, const chtype *chstr, int n); DESCRIPTION
These routines copy chstr into the window image structure at and after 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 of characters that will fit on the line. The window cursor is not advanced, and these routines work faster than waddnstr. On the other hand, they do not perform any kind of check- ing (such as for the newline, backspace, or carriage return characters), they do not advance the current cursor position, they do not ex- pand 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. RETURN VALUES
All routines return the integer ERR upon failure and OK on success (the SVr4 manuals specify only "an integer value other than ERR") upon successful completion, unless otherwise noted in the preceding routine descriptions. 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. NOTES
Note that all routines except waddchnstr may be macros. PORTABILITY
These entry points are described in the XSI Curses standard, Issue 4. SEE ALSO
ncurses(3NCURSES). Comparable functions in the wide-character (ncursesw) library are described in add_wchstr(3NCURSES). addchstr(3NCURSES)
