[omniORB] Who cleans up CORBA::string_dup'd memory?

[Brecht Vermeulen]

Hi Mark,

string_dup does a deep copy, so indeed you have a copy of the string and
you have to clean up the memory !

of course if you assign it to a string_var, the _var will do it for you
:

CORBA::String_var test = CORBA::string_dup("");

this will clean up the memory when going out of scope.

For arguments in a function, the caller has to take over the management
for inout, out and return arguments.

regards,
Brecht
