好用的win32线程封装类

废话不说，先上代码，此代码源于Applied C++书

<pre name="code" class="cpp">#ifndef _win32_thread_h_
#define _win32_thread_h_

// thread.h
//  win32 thread wrapper.

#ifndef WIN32
#error This version of cThread is only valid on win32 platforms
#endif

// We want this to be compatible with MFC and non-MFC apps
#ifdef _AFXDLL
#include <afx.h>
#else
#include <windows.h>
#endif

#include <process.h>    // _beginthread(), _endthread()
#include <iostream>

class cThread
{
public:
cThread  () : threadid_ (-1) {}
~cThread () { if (threadid_ != -1) stop();}

int threadid () const { return threadid_;}

bool start ()
{
threadid_ = _beginthreadex (0, 0, thread_, this,
CREATE_SUSPENDED, (unsigned int*) &threadid_);
if (threadid_ != 0)
ResumeThread ((HANDLE)threadid_);
return (threadid_ != 0);
}
// Start the thread running

bool stop  ()
{
TerminateThread ((HANDLE) threadid_, -1);
return true;
}
// Stop the thread. Ungraceful and may result in locking/resource problems.

bool wait (unsigned int seconds = 0)
{
DWORD wait = seconds * 1000;
if (wait == 0) wait = INFINITE;
DWORD status = WaitForSingleObject ((HANDLE) threadid_, wait);
return (status != WAIT_TIMEOUT);
}
// Wait for thread to complete

void sleep (unsigned int msec) { Sleep (msec);}
// Sleep for the specified amount of time.

protected:
int threadid_;

static unsigned int __stdcall thread_ (void* obj)
{
// Call the overriden thread function
cThread* t = reinterpret_cast<cThread*>(obj);
t->thread ();
return 0;
}

virtual void thread () {
_endthreadex (0);
CloseHandle ((HANDLE) threadid_);
}
// Thread function, Override this in derived classes.
};

#endif // _win32_thread_h_

使用，从cThread派生，实现其thread()函数， 然后创建类的实例，调用start（）成员函数即可

#include "thread.h"
#include <stdio.h>
class CTest : public cThread
{
void thread ();

};

void CTest::thread()
{
for(int i=0;i<10;i++)
{
printf("thread\n");
Sleep(1000);
}

}
int main(int argc,char** argv)
{
CTest test;
test.start();

return 0;
}
