Inter-Process Communication in C: Pipes and Message Queues In operating systems, a process is the basic unit of resource allocation, and inter-process communication (IPC) refers to the mechanisms that allow different processes to exchange data and information. The C language provides several ways to implement IPC, with the two most commonly used methods being pipes … Read more
▼ Click the card below to follow me ▲ Click the card above to follow me The Python multiprocessing library, Multiprocessing, is simply a savior for parallel computing! Imagine you have a bunch of compute-intensive tasks; the traditional single-threaded approach is like a snail climbing a mountain, while Multiprocessing is like installing a turbocharger. Basic … Read more
01 Introduction Ubus is the inter-process communication mechanism in OpenWRT, which simplifies the implementation of inter-process communication. The foundation of ubus is the UNIX Socket, which is a local socket that is more efficient and reliable compared to traditional network communication sockets. 1.1 Model Architecture UNIX Socket adopts a C/S model architecture, divided into server … Read more
C Language Interview: Signal Handling and Inter-Process Communication In modern operating systems, inter-process communication (IPC) and signal handling are two very important concepts. In C language interviews, examiners often focus on these two topics as they involve crucial aspects of system programming. This article will detail the basic concepts of signal handling and inter-process communication, … Read more
Implementing Shared Memory in C: IPC Mechanism In operating systems, Inter-Process Communication (IPC) is a mechanism that allows different processes to exchange data. Shared memory is an important method of IPC that allows multiple processes to access the same physical memory. This method is fast and efficient, making it suitable for applications that require frequent … Read more
Introduction Processes in Python from multiprocessing import Process import time def print_numbers(): for i in range(10): time.sleep(1) print(i) def print_letters(): for letter in 'abcdefghij': time.sleep(1) print(letter) if __name__ == '__main__': process1 = Process(target=print_numbers) process2 = Process(target=print_letters) process1.start() process2.start() process1.join() # join method is used to wait for the process to finish process2.join() —— $ python … Read more
Follow,Star Public Account to not miss exciting content Source: Embedded Miscellaneous Although my practical development experience with Linux is still limited, I am aware that there are several methods for inter-process communication: pipes, message queues, shared memory, sockets, etc. In a certain project, MQTT was used as the method for inter-process communication, which felt quite … Read more
A Comprehensive Guide to Python Multiprocessing Programming Implementing concurrent programming in Python is an important means to enhance program performance, and multiprocessing programming is an effective way to overcome the limitations of the Global Interpreter Lock (GIL). The multiprocessing module in the Python standard library provides developers with a complete solution for multiprocessing. This article … Read more
Introduction The previous article shared: “A Simple Understanding of MQTT and Mosquitto”, which only covered some concepts of MQTT and an introduction to Mosquitto. Then readers urged for more: In this article, we will share an example of using MQTT for inter-process communication. We will modify the comprehensive demo from the previous article “Examples of … Read more
