LIBRARY

Curses Library (libcurses, -lcurses)

SYNOPSIS

#include <curses.h>
int
addstr(const char *string);
int
addwstr(const wchar_t *string);
int
waddstr(WINDOW *win, const char *string);
int
waddwstr(WINDOW *win, const wchar_t *string);
int
mvaddstr(int y, int x, const char *string);
int
mvaddwstr(int y, int x, const wchar_t *string);
int
mvwaddstr(WINDOW *win, int y, int x, const char *string);
int
mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *string, int len);
int
addnstr(const char *string, int len);
int
addnwstr(const wchar_t *string, int len);
int
waddnstr(WINDOW *win, const char *string, int len);
int
waddnwstr(WINDOW *win, const wchar_t *string, int len);
int
mvaddnstr(int y, int x, const char *string, int len);
int
mvaddnwstr(int y, int x, const wchar_t *string, int len);
int
mvwaddnstr(WINDOW *win, int y, int x, const char *string, int len);
int
mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *string, int len);

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.
