NAME¶

addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr, mvwaddnstr - add a string of characters to a curses window and advance cursor

SYNOPSIS¶

#include <curses.h>

int addstr(const char *str);
 
int addnstr(const char *str, int n);
 
int waddstr(WINDOW *win, const char *str);
 
int waddnstr(WINDOW *win, const char *str, int n);
 
int mvaddstr(int y, int x, const char *str);
 
int mvaddnstr(int y, int x, const char *str, int n);
 
int mvwaddstr(WINDOW *win, int y, int x, const char *str);
 
int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n);

DESCRIPTION¶

These routines write the characters of the (null-terminated) character string str on the given window. It is similar to calling waddch once for each character in the string. The four routines with n as the last argument write at most n characters. If n is -1, then the entire string will be added, up to the maximum number of characters that will fit on the line, or until a terminating null is reached.

RETURN VALUE¶

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. X/Open does not define any error conditions. This implementation returns an error if the window pointer is null or if the string pointer is null or if the corresponding calls to waddch return an error. 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 of these routines except waddstr and waddnstr may be macros.

PORTABILITY¶

All these entry points are described in the XSI Curses standard, Issue 4. The XSI errors EILSEQ and EOVERFLOW, associated with extended-level conformance, are not yet detected.
