Question about the tibco library

 HI all

It is about http://code.kx.com/wsvn/code/kx/kdb%2B/c/feed/rv.c, just wonder, why the function to be overload is “upd”? It make the process connect to tibco rv is not able to subscript to ticket plant, because the ticket plant update function is also upd, isn’t it?

I think that is just convention. 

The message published by the TP (or a standard publisher based on u.q) is a “upd” message but that doesn’t have any special meaning within kdb+. 

rv.c calls back into the q process with a “upd” message which then must be defined in the q process.  It’s not the same as the upd in a tick set up, and you can call it something else if you like (you’ll have to rebuild the rv shared object)

Thanks
