如何在C for Windows中创建多线程? [英] How can i create a multithread in C for windows?

问题描述

我不知道如何在C中创建线程，我看到了有关pthread.h库的评论，但后来我听说它仅适用于Linux OS，我有一个计时器功能，我想用该功能，但是如果有人可以为我提供带有线程的简单代码，或者告诉我需要放置什么内容以及函数的参数，我既不知道我需要使用的库也不是编写代码的语法.

I dont know how can I make threads in C, i saw a review about pthread.h library but then i heard that its only for Linux OS, i have a function that its a timer, i want to created a thread with that function but i dont know either the library i need to use and syntax's to write the code, if someone could provide me a simple code with threads, or tell me what things i need to put and the parameter of the functions.

这里是我创建的功能，它在用户申请的特定时间进行倒计时: 我需要使用该函数创建线程.

Here its the function i create that countdown the specific time the user apply: i need to make a thread with that function.

功能(倒数):

#include <stdio.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

void countdown(int second)
{
    int secs = 1;
    time_t unix;
    struct tm * timeinfo;
    time(&unix);
    timeinfo = localtime(&unix);
    int t1 = timeinfo->tm_sec;
    int t2 = timeinfo->tm_sec;
    int i = 0;

    while(1 == 1)
    {
       time(&unix);
       timeinfo = localtime(&unix);
       if((t1 + i)  == timeinfo->tm_sec)
       {
              system("cls");
              printf("Time left %d\n", timeinfo->tm_sec - t2 - second);
              i++;
       }
       if(timeinfo->tm_sec >= (t1 + second))
       {
           system("cls");
           puts("Your time its done");
           break;
       }

    }
}

int main()
{
    int limit;
    printf("How much time would you like (In secs): ");
    scanf("%d", &limit);
    countdown(limit);

    system("PAUSE");
    return 0;
}

这是winapi线程的简单指南

话虽这么说，C是一种简约语言，没有像Java这样的内置线程(也没有大量额外的库).它被认为是在此基础上构建的一种通用语言.在类Unix系统上，除了ANSI/ISO标准(属于posix标准的一部分)之外，还有系统范围的标准c库，pthread是posix-threads. Windows C库是MS用自己的方式做事的.您可以使用提供多操作系统支持的框架，例如glib或qt(Windows，Linux，其他* nix).还有一些端口和兼容性层，可在Windows内部使用posix工具.除了库之外，Cigwin还为您提供了完整的posix环境，MinGW编译器允许您在win32层之上使用posix函数的端口.

That being said, C is a minimalistic language, does not have built-in threading like java (nor the enormous extra libraries). It was meant as a general language to build on top of it. On Unix-like systems there are system wide standard c libraries beyond the ANSI/ISO standard, which are part of the posix standard, the pthreads are posix-threads. Windows C libraries are MS makes things their own way. You can use frameworks that provides multi-OS support like glib or qt (Windows, Linux,other *nix). There are also ports and compatibility layers to use posix facilities inside windows. Cigwin gives you a full posix environment besides the libraries, The MinGW compiler allows you to use ports of posix functions on top of win32 layers.

像glib和qt这样的框架最好使您的代码保持多平台，它们隐藏了操作系统的细节，从而允许使用更通用的方法.

Frameworks like glib and qt are best to keep your code multi-platform, they hide the OS specifics, allowing a more general approach.

glib是用于GUI开发的GTK库的一部分，而QT也是GUI开发框架，但使用C ++.

glib is part of the GTK libraries for GUI development and QT is also a GUI development framework but in C++.
