    Patent number: 5265250
    Abstract: Apparatus and method for performing an application-defined operation on data as part of a system-defined operation on the data. The apparatus and method are embodied in a distributed transaction processing system in which processes running on component systems which may be heterogeneous interact according to the client-server model. In the apparatus and method, a type is associated with the data and application-defined operations which are part of certain system-defined operations are defined for each type. The system-defined operations which the application-defined operations are part of include allocation, reallocation, and deallocation of buffers and sending buffers between clients and servers using remote procedure calls. In the allocation and reallocation operations, the application-defined operation is initialization; in the deallocation operation, it is uninitialization.
