B4J Question Reading from custom file descriptor

[wl]

Hi,

I'm trying to write a checkpassword Java console app for Dovecot.

I found that in a bash script I should read data from file descriptor 3
(eg:
1
2
read-d$'\0'-r-u3USER
read-d$'\0'-r-u3PASS
)

I'm know on how to read from stdin (reader.Initialize (sys.getField('in")), but how to read from FD 3 ?

Thanks

Ok, guess I found it ?

reader.Initialize(File.OpenInput("/dev/fd/", "3"))

Thanks Erel, I was aware of this example but this reads from STDIN (FD 0 if I'm not wrong). I needed to read from FD 3
