Abstract

An interprocess communication facility in a processor system provides for communication of data between at least two processes. The facility supports a plurality of different data transfer modes which are provided by storage management services of the processor or processors. A process interface provides a common interface for each communicating process to select data transfer modes independently of the data transfer mode chosen by the other communicating process. A data access control function is coupled to the process interface and to the storage management services. The data access control function controls the use of the storage management services as a function of the transfer modes chosen by the communicating processes. It is transparent to the processes as to which transfer mode was chosen by each other.
