Abstract: A technique for providing support for multiple calling conventions for methods and procedures that return structures is provided. A source code of a client program may be compiled by either of two compilers, wherein one compiler employs a calling convention that is different from the first one. A binary library containing a procedure and a converter for each procedure returning a structure to a client program, is provided to support two calling conventions. If the client program is compiled by a compiler using a first calling convention, the program is compiled such that it calls the procedure directly and receives a result, a structure, via the first calling convention. Compiling the client program with a compiler using the second conventions results in calls to the procedure being routed to the converter, which calls the associated procedure, using the first calling convention.

Abstract: A method, system and program for supporting a dynamic bind between a derived class and its parent class. A processor provides for the registration of class objects and dynamic binding of derived class objects to their parent class objects based on the registration mechanism. The SOM object model removes static references to class objects by having all the parent class information available at runtime through the parent class object. Thus, when the derived class implementation needs information about the size of the parent class state data structure, the addresses of the parent class method procedures, or access to the parent class method procedure table the appropriate information is retrieved from the parent class object.
