I am not completely knowledgable in the stream classes of Tango that do 
serialization, but I don't think there's anything to do what you want.  It 
would be difficult for the stream class to know the exact layout of your 
struct, so how would it know when to output strings?  I think DataStream is 
what you are looking for, but it will only output a block of data.

Again, not completely knowledgable.  You might try asking on the Tango 
forums to get the attention of some of the Tango devs that don't pay 
attention to the NG.
