C language implementation randomly generated 0 or 1

The RAND function requires a system-supplied seed to generate a sequence of pseudo-random numbers before generating a random number, and Rand produces a series of random numbers based on the value of the seed. If the seed provided by the system does not change, the sequence of pseudo-random numbers generated by each call to the RAND function is the same. Srand (unsigned seed) alters the seed value provided by the system through the parameter seed, which allows the sequence of pseudo-random numbe

Usage and differences of os._exit () and Sys.exit (), exit (0) and exit (1) in Python

Os._exit () and Sys.exit ()Os._exit () vs Sys.exit ()OverviewPython's program has two exit methods: Os._exit (), Sys.exit (). This article describes the differences and choices between the two approaches.Os._exit () will terminate the Python program directly, and all subsequent code will not continue to execute.Sys.exit () throws an exception: Systemexit, if the exception is not captured, the Python interpreter exits. If there is code to catch this exception, the code will still execute. Catchin

Linux kernel stacks using methods process 0 and Process 1 "go"

the stack is the stack that the kernel program uses itself. The addresses given are approximate values, which are related to the actual setup parameters at compile time. These address locations are found in the System.map file that was generated when the kernel was compiled. Figure 5-23 The stack used by the kernel when it enters protection mode (3) initialization (MAIN.C) is used in the INIT/MAIN.C program until the execution Move_to_user_mode () C
