[orbitcpp-list] diff String_mgr String_var

[Andreas K. <ak...@ix...>]

Hi again Phil,

the only difference between String_var and String_mgr i have been able
to detect was that _mgr does not free anything in its destructor. in the
comment above its declaration, you state it also initializes to an
empty, rather than a null string, but this does not appear to be the
case. what exactly should be done differently? (since i'm integrating
the _mgr with my _var templates, the only difference being made by a
bool template parameter)

Err.. Yes - you're right. I need to check the spec to see if this is
what indeed is required.

string_mgr definitely needs to not free anything in the destructor
(since CORBA_free on a variable length struct or sequence also deep
frees the contents). I'm not sure if it also needs to initialise to an
empty string - it depends on whether the C marshallers can cope with
NULL strings in sequences and structs.

Cheers,

Phil.
