问题 I am currently working on an assembly program, but I need to make the program wait every once in a while. So, I have been using int 15h/ah = 86h, but for some reason DosBox is giving me a hard time, and the program either gets confused with pixels (wierd colors) or in the worse case; crash. Can someone please help me? 回答1: I had this issue as well. Based on the answer at Problems with BIOS delay function (INT 15h / AH = 86h), I was able to get it working by making sure to set AL to zero

问题 The context is like this: a thread tries to lock a already locked mutex the thread is put to sleep/blocking after some while, the mutex is unlocked Q1) What will happen then ? will the thread be immediately put back to running? Or kernel will still wait the running thread consume its time slice and schedule the waiting thread normally? Q2) What if the mutex is not unlocked forever? How does the kernel determine to keep the thread waiting? 回答1: Will the thread be immediately put back to

问题 I am using react redux, and trying to call rest-api, and return the data. The fetch is asynchronous, and I need to return value only when the fetch is finished. I tried the following, but this didn't work properly (there is no 'wait' on the line that is with asterisks) - What shall I do? Code: ----- var _getData = function() { return new Promise((resolve, reject) => { let options = { method: 'GET', } let _url = "my web return json"; fetch(_url, options) .then(response => response.json(). then

问题 I am trying to write a c++ program that creates a child process, runs a command and pipes the output back to the input of a command the parent is running. I have the parent execute the wait(NULL) or wait((void*)pid) command but it does not wait. here is the code: #include <string.h> #include <fstream> #include <iostream> #include <unistd.h> #include <stdio.h> #include <sys/wait.h> using namespace std; int main(int argc, char * argv[]) { char* commands[strlen(argv[1])]; char *command = NULL;
