LIBRARY

Curses Library (libcurses, -lcurses)

#include <curses.h>

int
underscore(void);

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.

RETURN VALUES

These functions always return 1.

STANDARDS
