Inter-process Communication

<programming, operating system> (IPC) Exchange of data between one process and another, either within the same computer or over a network. It implies a protocol that guarantees a response to a request. Examples are Unix sockets, {RISC OS}'s messages, OS/2's Named Pipes, Microsoft Windows' DDE, Novell's SPX and Macintosh's IAC. Although IPC is performed automatically by programs, an analogous function can be performed interactively when users cut and paste data from one process to another using a clipboard. (1995-12-14)

Local Inter-Process Communication

IN MICROSOFT'S WINDOWS NT OPERATING SYSTEMS

Lightweight procedure call; ALPC; Local Procedure Call; Lightweight Procedure Call; Asynchronous Local Inter-Process Communication

The Local Inter-Process Communication (LPC, often also referred to as Local Procedure Call or Lightweight Procedure Call) is an internal, undocumented inter-process communication facility provided by the Microsoft Windows NT kernel for lightweight IPC between processes on the same computer. As of Windows Vista, LPC has been rewritten as Asynchronous Local Inter-Process Communication (ALPC, often also Advanced Local Procedure Call) in order to provide a high-speed scalable communication mechanism required to efficiently implement User-Mode Driver Framework (UMDF), whose user-mode parts require an efficient communication channel with UMDF's components in the executive.

Inter-process communication

In computer science, inter-process communication or interprocess communication (IPC) refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.

IPC is very important to the design process for microkernels and nanokernels, which reduce the number of functionalities provided by the kernel. Those functionalities are then obtained by communicating with servers via IPC, leading to a large increase in communication when compared to a regular monolithic kernel. IPC interfaces generally encompass variable analytic framework structures. These processes ensure compatibility between the multi-vector protocols upon which IPC models rely.

An IPC mechanism is either synchronous or asynchronous. Synchronization primitives may be used to have synchronous behavior with an asynchronous IPC mechanism.
