C Language Interview: Signal Handling and Inter-Process Communication

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

Signal Handling in C: Capturing and Managing Signals

Signal Handling in C: Capturing and Managing Signals In C, a signal is a mechanism used to notify a program that a specific event has occurred. These events may be triggered by external systems, such as user input (like Ctrl+C), software faults, or timer expirations. Signals can interrupt the normal execution flow of a program … Read more

Signal and Interrupt Handling in C++

Signal and Interrupt Handling in C++ In operating systems, signals and interrupts are two important process control mechanisms. Signals are typically used to notify a program of certain events, while interrupts are responses to hardware events or changes in conditions. In C++ programming, using signals allows for asynchronous event handling, making it crucial to master … Read more

Embedded Linux: Asynchronous I/O

Click the aboveblue text to follow us In embedded Linux, asynchronous I/O (AIO) is a powerful I/O model that allows processes to continue executing other tasks while waiting for I/O operations to complete. Compared to I/O multiplexing mechanisms (such as select and poll), asynchronous I/O uses a signal notification mechanism, allowing processes to avoid repeatedly … Read more
