问题描述

我已经成功地创建使用的CreateThread()。单线程

I have successfully created a single thread using CreateThread().

现在我想创建'N'的线程数量,但每一个不同的ThreadProc的()。

Now I want to create 'n' number of threads but each with a different ThreadProc().

我曾尝试以下code,但使用它,N被创建的线程数都执行相同的任务(因为ThreadProc的()函数自动对焦的所有线程是一样的。)

I have tried the following code but using it, 'n' number of threads are created all performing the same task (since Threadproc() function af all threads is same.)

    //Start the threads
for (int i=1; i<= max_number; i++) 
{
CreateThread( NULL, //Choose default security
              0, //Default stack size
              (LPTHREAD_START_ROUTINE)&ThreadProc,
              //Routine to execute. I want this routine to be different each time as I want each  thread to perform a different functionality.
              (LPVOID) &i, //Thread parameter
              0, //Immediately run the thread
              &dwThreadId //Thread Id
            ) 
}

有什么办法,我可以创造'N'数量的线程每一个不同的线程程序?

Is there any way I can create 'n' number of Threads each with a different Thread procedure?

推荐答案

试试这个:

DWORD WINAPI ThreadProc1(  LPVOID lpParameter)
{
  ...
  return 0 ;
}

DWORD WINAPI ThreadProc2(  LPVOID lpParameter)
{
  ...
  return 0 ;
}

...

typedef DWORD (WINAPI * THREADPROCFN)(LPVOID lpParameter);

THREADPROCFN fntable[4] = {ThreadProc1, ThreadProc2, ...} ;

//Start the threads
for (int i = 0; i < max_number; i++) 
{
  DWORD ThreadId ;

  CreateThread( NULL,
                0,
                (LPTHREAD_START_ROUTINE)fntable[i],
                (LPVOID) i,
                0,
                &ThreadId
              ) ;
}

这将启动MAX_NUMBER线程与在fntable定义不同的线程程序(TreadProc1,ThreadProc2等)。

This will start max_number threads with different thread procedures (TreadProc1, ThreadProc2, etc.) as defined in fntable.
