variables, buffers, and so on.(3) When the parent process learns that the child process is terminated, it is the responsibility to use the wait system call for the child process. This wait function takes out the exit information of the child process from the kernel and empties the space occupied by the information in kernel.8.Linux Signal Basics(1) compared to other inter-process communication methods (interprocess communication, such as pipe, shared

SIGWINCH/* Window size changes * * When the process adjusts the line or column of the terminal (such as increasing the size of your xterm), the sigwinch signal is sent to the process. The default behavior is to discard the signal. #define SIGUSR1/* User Defined signal 1 * * #define SIGUSR2/* User Defined Signal 2 * * SIGUSR1 and SIGUSR2 These two signals are designed to be specified by the user. They can be set up to do whatever you need. In other words, the operating system does not have a

in this series, the author outlines several main means of inter-process communication between Linux. Pipelines and well-known pipelines are among the earliest inter-process communication mechanisms, pipelines can be used for communication between affinity processes, and well-known pipelines overcome the limitations of pipe without name, so that, in addition to having the functionality of a pipeline, it allows for inter-process communication without af

People who have played Linux will know that there are really a lot of commands in Linux, but people who have played Linux have never bothered by the fact that Linux commands are so many, because we only need to master the commands we use most often. Of course you can also use to find the man, he will help you solve a l

Compile the linux0.00 kernel (full Linux Kernel Analysis-based on the 0.12 kernel) I have bought a fully-analyzed Linux kernel written by Zhao Ke-based on the 0.12 kernel. It seems that the principles of the first four chapters have never had the courage to practice them by myself. Recently, I have made up my mind to take a good look at this book, and I plan to write some study notes to record some gains an
