try this on 2.1.109-vanilla (2.1.105 is ok). It should display digital
clock on the upper right corner of the screen:
--- cut here ---
#include <fcntl.h>
#include <time.h>
void
fatal(char *s) {
perror(s);
exit(1);
}
int
main(){
int fd;
int cols = 80;
time_t tid;
struct tm *t;
char tijd[10];
if((fd = open("/dev/vcs0", O_WRONLY)) < 0)
fatal("/dev/vcs0");
while(1) {
lseek(fd, cols-9, 0);
tid = time(0);
t = localtime(&tid);
sprintf(tijd, " %02d:%02d:%02d", t->tm_hour, t->tm_min, t->tm_sec);
write(fd, tijd, 9);
usleep(500000L);
}
}
--- cut here ---
It seems that writing to /dev/vcs0 makes the console singing "Ugh,
lalala, I love you baby..."
