IPC provides synchronous (RPC) and asynchronous communication features allowing threads to communicate and synchronize when they do not share memory. Communications rely on the exchange of messages through ports. See also Remote Procedure Call (RPC), asynchronous communication mode, static and dynamic identifiers, and MIPC.
(1.) Used for programs to communicate data to each other and to synchronize their activities. Semaphores, signals, and internal message queues are common methods of inter-process communication. (2.) In Enhanced X-Windows, a communication path. See also client.
You use inter-process communication, or IPC, when two or more processes need to communicate. The communication can take place using databases, shared memory, semaphores, or sockets.
System calls that allow a process to send information to another process. There are several ways of sending information to another process: signals, pipes, shared memory, message queues, semaphores, streams, or sockets.
Inter-Process Communication (IPC) is a set of techniques for the exchange of data between two or more threads in one or more processes. Processes may be running on one or more computers connected by a network. IPC techniques are divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC).
