Abstract
The present invention provides a system for using door translation to perform inter-process communication. The system enables a legacy application program to invoke traditional operations, such as READ and WRITE operations, which would otherwise be unavailable in a doors environment. Transparent to the client process, the system of the present invention translates the otherwise unavailable operation into a door call. Bound by its limitations and constraints, the server process performs a service in response to the door call. The system comprises a system call handler, such as a generic file system, which receives a file operation request from a client process. A door invocation handler, which includes a translator, determines the appropriate server process capable of performing a service corresponding to the operation request, translates the operation request into a door call to the server process, and invokes the door call. The server process performs its service and sends a response back via the operating system kernel to the client process.
