Signal Handling in C: Capturing and Processing Signals

In C, a signal is an asynchronous event used to notify a program that a certain condition has occurred. Signals can be generated by the operating system, hardware, or the program itself. Common signals include process termination and illegal memory access. In this article, we will introduce how to capture and handle these signals in … Read more

Applications and Examples of Signal Handling in C Language

Applications and Examples of Signal Handling in C Language Signal handling is an important concept in operating systems and programming, especially in C language, as it allows programs to respond to asynchronous events such as user input, timer expirations, or signals from other external devices. In this article, we will explore the basic principles of … Read more
