[Info-vax] LAN statistics...

[Vala]

I'm trying to get usage data of the network interfaces installed
separated by protocol.
I can't find one system service that provides this information.
I searched through the system service SYS$QIO using a function
modifier, but could not find.
I'm looking here for some help before trying to access system memory
structures.
If my code starts from "SCS$GQ_CONFIG", looking inside system blocks
(SB), then into device data blocks (DDB) and finally into unit control
blocks (UCB) lists, I can see the information i'm looking for.
Of course I must do this in KERNEL mode, but i'm trying to obtain this
data using other mechanisms avoiding possible system crashes.
Thanks in advance.

Best regards, Fernando Vallarino.
