добавить строку символов в окно curses и продвинуть курсор (add a string of characters to a curses window and advance cursor)
Имя (Name)
addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr,
mvwaddstr, mvwaddnstr - add a string of characters to a curses
window and advance cursor
Синопсис (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);
Описание (Description)
These functions write the (null-terminated) character string str
on the given window. It is similar to calling waddch once for
each byte in the string.
The mv functions perform cursor movement once, before writing any
characters. Thereafter, the cursor is advanced as a side-effect
of writing to the window.
The four functions with n as the last argument write at most n
bytes, or until a terminating null is reached. If n is -1, then
the entire string will be added.
Возвращаемое значение (Return value)
All functions return the integer ERR upon failure and OK on
success.
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. If an error is
returned by the wmove, no characters are added to the window.
If an error is returned by waddch (e.g., because the window is
not large enough, or an illegal byte sequence was detected) only
part of the string may be added. Aside from that, there is a
special case in waddch where an error may be returned after
successfully writing a character to the lower-right corner of a
window when scrollok is disabled.
Примечание (Note)
All of these functions except waddnstr may be macros.
