the role of DUP and dup2DUP and dup2 are also two very useful calls that are used to copy the descriptor of a file. They are often used to redirect stdin, stdout, and stderr of processes. The prototypes for these two functions are as

When the process starts running, three files of the corresponding device are automatically opened. They are standard input, output, and error streams, which are represented by the Global File pointers stdin, stdout, and stderr respectively, the

There is a class named open3 in ruby that can be used to execute system commands. However, after Ruby is installed in WINXP, open3 supports Linux by default. If you run the code, the fork () cannot be found () method error. Fortunately there is a

The Linux commands to be executed in Java programs mainly depend on two classes: process and runtime. First, let's take a look at the process class: [Plain] View plaincopyprint? Processbuilder. Start () and runtime.exe C create a local process

Each process has a task_struct struct in the Linux kernel to maintain process-related information, known as process descriptor. In operating system theory, it is called a process control block (PCB, process control block ). Task_struct has a pointer
