I’ve been using ncurses for a project. I’m using wide characters so i found functions to display those in ncurses: mvwaddwstr and mvwaddnwstr. But when I compile my program it gives warning: warning: implicit declaration of function ‘mvwaddnwstr’; did you mean ‘mvwaddnstr’? [-Wimplicit-function-declaration] and similar warning for mvwaddwstr also. Although the program compiles and runs successfully so i’ve been ignoring this for long time.
