Today, a friend went to a good foreign company to interview for a linux development position. The interviewer gave the following question: The following C program is provided and compiled using gcc in linux: 1 # include "stdio. h" 2 # include "sys/types. h" 3 # include "unistd. h" 4 5 int main () 6 { 7 pid_t pid1; 8 pid_t pid2; 9 10 pid1 = fork (); 11 pid2 = fork (); 12 13 printf ("pid1: % d, pid2: % d/n", pid1, pid2 ); 14} The requirements are as fol

Operating System interview: Program, process, thread Note: There are many errors and vulnerabilities in the operating system of the "Interview Guide". I have rewritten the relevant books and opinions for your reference. 1. Programs, processes, and threads 1. programs and processes. A process consists of two parts: 1) t

) The scheduler dispatches the processes in the second queue only when the first queue is idle, and only if the 1th~ (i-1) queue is empty, the process in queue I is scheduled to run. If the processor is servicing a process in queue I, and a new process enters a higher priority queue (1~ (i-1)), then the new process wil

A: In fact, most of WinDOS's process communications are ported to UNIX, WinDOS's clipboard, file mappings, and so on, all of which can be found in shared storage for UNIX process communication. 　　FAQ5: What is the relationship between interprocess communication and inter

all of the non-static parts into the heap memory. At this point, you understand the Java syntax, why the static member is "class name. Member", and non-static member is "object. Member". Because the owning relationship is different. So we start looking for non-static members, with J and a building block. So it is to apply the space to J first and then run the print ("J") method to give the return value of the method to J. So, the first paragraph of the program printed the results: print: Therea

In this example, we can calculate the probability that everyone's birthdays are different, that is: 365/365 * 364/365 * 363/365 * ... * (365-49)/365, so that at least two people birthday the same probability is the value of this.
