On Linux & OS X, we use a socketpair (). A named pipe is allocated for each renderer process for communication with the browser process. The pipes are used in asynchronous mode to ensure that neither end is blocked waiting for the other.5.1 Interprocess Communication Inter-Process Communication (IPC) is a set of techniques for the exchange of data among 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, 行程間通訊（英語： Inter-Process Communication ，簡稱 IPC ），指至少兩個行程或執行緒間傳送資料或訊號的一些技術或方法。 行程是電腦系統分配資源的最小單位（嚴格說來是執行緒）。每個行程都有自己的一部分獨立的系統資源，彼此是隔離的。 Inter process communication (IPC) is a mechanism which allows processes to communicate with each other and synchronize their actions. The communication between these processes can be seen as a method of co-operation between them. Processes can communicate with each other through either of these techniques: Shared Memory. Message passing.

Inter-Process Communication (IPC) in Linux. IPC mechanisms in Linux facilitate complex communications between processes. This includes shared memory, message queues, and semaphores. Each type of IPC serves specific purposes, and understanding their applications and limitations is crucial for efficient system design and operation.Direct Communication. Both sender and receiver must know each other’s identity. • send(Q, message): send. message to process Q. receive(P, message): receive message from process P. OS establishes link automatically when message sent. Address symmetry: both P and Q must name each other to communicate. …
