CURSES_UNDERSCORE(3) Library Functions Manual CURSES_UNDERSCORE(3)

curses_underscore, underscore, underend, wunderscore, wunderend
curses underscore attribute manipulation routines

Curses Library (libcurses, -lcurses)

#include <curses.h>

int
underscore(void);

int
underend(void);

int
wunderscore(WINDOW *);

int
wunderend(WINDOW *);

These functions manipulate the underscore attribute on stdscr or on the specified window.

The underscore() function turns on the underscore attribute on stdscr. The underend() function turns off the underscore attribute on stdscr.

The wunderscore() and wunderend() functions are equivalent to underscore() and underend(), respectively, excepting that the attribute is manipulated on the window specified by win.

The underscore() and underend() functions are equivalent to wattron(A_UNDERLINE) and wattroff(A_UNDERLINE), respectively.

These functions always return 1.
