FIFO question

[Alain Rolle <Alain.Rolle@rug.ac.be>]

Hello,

I have two modules, in which FIFO 's are created.
Module 1 : RTF 1 and RTF 2
Module 2 : RTF 3 and RTF 4

To these modules, two linux tasks are connected, in which the well known


fdX = open("/dev/rtfX",...); (for both associated FIFO's;one to  write
to, one to read from)

is done. 

Yet, when I look at the fdX's, it seems that in both linux tasks they have
the values 3 and 4. (where one would expect at least s.th. like 3,4,5,6,
or even better : just 1,2,3,4. )

Is this normal or not ?

Thanks,

Alain.
