How to inter process communication

Posted on 14 Ekim 2015 in Programlama by

File A record stored on disk, or a record synthesized on demand by a file server, which can be accessed by multiple processes. Most operating systems
Signal A system message sent from one process to another, not usually used to transfer data but instead used to remotely command the partnered process. Most operating systems
Socket A data stream sent over a network interface, either to a different process on the same computer or to another computer on the network. Most operating systems
Message queue An anonymous data stream similar to a socket, usually implemented by the operating system, that allows multiple processes to read and write to the message queue without being directly connected to each other. Most operating systems
Pipe A two-way data stream between two processes interfaced through standard input and output and read in one character at a time. All POSIX systems, Windows
Named pipe A pipe implemented through a file on the file system instead of standard input and output. Multiple processes can read and write to the file as a buffer for IPC data. All POSIX systems, Windows
Semaphore A simple structure that synchronizes multiple processes acting on shared resources. All POSIX systems, Windows
Shared memory Multiple processes are given access to the same block of memory which creates a shared buffer for the processes to communicate with each other. All POSIX systems, Windows
Message passing Allows multiple programs to communicate using channels, commonly used in concurrency models. Used in MPI paradigm, Java RMICORBADDSMSMQMailSlotsQNX, others
Memory-mapped file A file mapped to RAM and can be modified by changing memory addresses directly instead of outputting to a stream. This shares the same benefits as a standard file. All POSIX systems, Windows
