Well, try:
#include <stdlib.h>
#include <stdio.h>
#include <curses.h>
int
main(int argc,char** argv)
{
/* in curses(3X) manual page... */
initscr();
if (beep() !=3D OK)
printf("No OK\n"); fflush(stdout);
if (flash() !=3D OK)
printf("No Flash\n"); fflush(stdout);
return 0;
}
And read the curses manual page, you forgot to init
the screen.
