Could anyone tell me how to get "Attention Code" used in SPAttention call ?
I would like to use this call for notifying some events to client.
I am looking for the definition of this code in "Inside AppleTalk second
edition", however, I cannot find out yet.

The SPAttention codes are documented in the AppleShare 3.0 developers kit, 
available from Apda. 


The attention code sent in an Attention packet looks like this



(4 bits)|(12 bits)
  1234    XXXXXXXXXXXX


4-Bits (Attention code)
------

Bit
----

1 - Shutdown

2 - Server Crash

3 - Server Message

4 - Disconnect



The other 12 bits are the number of minutes until shutdown, or an extended 
bitmap.



See the Developers kit for more details.
