Device files / Listening for information ?

Hey. Ive got a usb bluetooth dongle on /dev/hci0. Is there anyway I can write a *small* application to get any information incoming from the dongle ? or is this not how you would do it ?

c++ language, btw.

Code:

int main(void)
{
  int fd;
  char buf[256];

  fd = open("/dev/hci0", O_RDONLY);

  read(buf, sizeof(buf), fd);
}

I'd imagine that's how you do it anyway. Parsing what you're reading in is a whole different ball of wax though

type 'man open' and hit [enter] at the commmand prompt.
