how to check if corba::WString is empty?

Question

Searched for this everywhere and finally came here. I have a CORBA::WString_var as input parameter to my function. How do I know if it's empty?

I think you need to consult your ORB vendor's documentation. If your ORB maps CORBA::WChar to std::wchar_t, then you can use the techniques in this answer.

It is a long time ago. But if I remember correctly you can cast the WString_var to a WCHAR* and check this for NULL.

You can't pass null strings across an IDL interface. – Brian Neal Mar 22 '11 at 12:57

Use variable.in() to get the pointer to the CORBA::WChar array, than you can check that
