strictly frank

hi, 
i am studying MB's example, frank, distributed with rtl-2.3 and can out
work out the mechanism of transfering data from the RT fifos to the
/dev/rtfx. 
i can see that the non-RT part, in the main() section, opens up 3 files:
/dev/rtf1, /dev/rtf2, /dev/rtf3. is that right?
in the end of main(), still in the non-RT space, the contents of the
above devices is printed.
later on in the RT part of the frank module, 5 fifos are created as
follows:

int init_module(void)
{
	-----
	-----
	---
	c[0] = rtf_create(1, 4000);
	c[1] = rtf_create(2, 4000);
	.
	.
	c[4] = rtf_create(5,100);
	----
	----
	-----
	rtf_create_handler(3, &my_handler);
	return 0;

}

i can also see that these are the fifos that are written to by the
thread_code(void *t) as follows:

thread_code(void *t){
	------
	-----	
	-----
	rtf_put(fifo, data[fifo -1], 6);
	-----
	-----
	----
return 0;
	}

i have not yet worked out how the data is transfered from the fifos that
were written to in the thread code to the files /dev/rtfx... that were
printed out in the end.
can anyone please let me know?

thanks in advance.
