[omniORB] basic question about sequences

[Michael]

Since we're using auto_ptr, boost::shared_ptr etc. a lot everywhere, I
personally prefer it the other way round :)
(actually I use a lot of STL constructs and have a little template
library for converting everything on return).

Anyway, you're right about initializing the out parameter, there
should've been be a line

seq_out = new seq_type;

in my example (but seq_out will never be NULL (but nil :)).

I just grepped through my codebase, and it appears I used out parameters
twice in 5 years :) I generally prefer returning structs/sequences
whatever, because out parameters make me feel ... bad inside :)

cheers
