My original code which worked under Visibroker C++ for Tornado
and omniORB2 used the template function:
template <class Type>
int
getObjectReference(Type **a, const char *name, CosNaming::NamingContext_var nc, int maxRetries)
{ ... }
The call to the function looked like the following (for an interface OCS::IAttributeDB)
OCS::IAttributeDB *obj;
getObjectReference( &obj, ... );
I get the compilation error "parse error before `,'" with either of the following
changes:
getObjectReference(Type::_ptr_type a, ...
getObjectReference(Type::_ptr_type *a, ...
If I add typename (similar to a function Ch. 18 of Advanced CORBA Programming with C++,
Henning & Vinoski) the following template compiles:
template <class Type>
int
getObjectReference(typename Type::_ptr_type a, ...
but I get the compilation error
no matching function for call to `getObjectReference (OCS::_objref_IAttributeDB *&, const char *, CosNaming::NamingContext_var, int)
when I try to call the function like so:
OCS::IAttributeDB_ptr obj;
getObjectReference( obj, ... );
I am not experienced with using templates so maybe I was just lucky
that what I had done previously worked.
Any advice would be greatly appreciated.
