一、使用_beginthreadex()需要的头文件支持#include // for _beginthread()
需要的设置:ProjectàSetting-->C/C++-->User run-time library
选择Debug Multithreaded
或者Multithreaded
。即使用: MT
或MTD
。
代码如下:
#include <stdio.h> #include <string> // for STL string class #include <windows.h> // for HANDLE #include <process.h> // for _beginthread() using namespace std; class ThreadX { private: int loopStart; int loopEnd; int dispFrequency; public: string threadName; ThreadX( int startValue, int endValue, int frequency ) { loopStart = startValue; loopEnd = endValue; dispFrequency = frequency; } static unsigned __stdcall ThreadStaticEntryPoint(void * pThis) { ThreadX * pthX = (ThreadX*)pThis; // the tricky cast pthX->ThreadEntryPoint(); // now call the true entry-point-function return 1; // the thread exit code } void ThreadEntryPoint() { for (int i = loopStart; i <= loopEnd; ++i) { if (i % dispFrequency == 0) { printf( "%s: i = %d\n", threadName.c_str(), i ); } } printf( "%s thread terminating\n", threadName.c_str() ); } }; int main() { ThreadX * o1 = new ThreadX( 0, 1, 2000 ); HANDLE hth2; unsigned uiThread1ID; hth2 = (HANDLE)_beginthreadex( NULL, // security 0, // stack size ThreadX::ThreadStaticEntryPoint, o1, // arg list CREATE_SUSPENDED, // so we can later call ResumeThread() &uiThread1ID ); if ( hth2 == 0 ) printf("Failed to create thread 1\n"); DWORD dwExitCode; GetExitCodeThread( hth2, &dwExitCode ); // should be STILL_ACTIVE = 0x00000103 = 259 printf( "initial thread 1 exit code = %u\n", dwExitCode ); o1->threadName = "t1"; ThreadX * o2 = new ThreadX( -100000, 0, 2000 ); HANDLE hth3; unsigned uiThread2ID; hth3 = (HANDLE)_beginthreadex( NULL, // security 0, // stack size ThreadX::ThreadStaticEntryPoint, o2, // arg list CREATE_SUSPENDED, // so we can later call ResumeThread() &uiThread2ID ); if ( hth3 == 0 ) printf("Failed to create thread 2\n"); GetExitCodeThread( hth3, &dwExitCode ); // should be STILL_ACTIVE = 0x00000103 = 259 printf( "initial thread 2 exit code = %u\n", dwExitCode ); o2->threadName = "t2"; ResumeThread( hth2 ); // serves the purpose of Jaeschke's t1->Start() ResumeThread( hth3 ); WaitForSingleObject( hth2, INFINITE ); WaitForSingleObject( hth3, INFINITE ); GetExitCodeThread( hth2, &dwExitCode ); printf( "thread 1 exited with code %u\n", dwExitCode ); GetExitCodeThread( hth3, &dwExitCode ); printf( "thread 2 exited with code %u\n", dwExitCode ); CloseHandle( hth2 ); CloseHandle( hth3 ); delete o1; o1 = NULL; delete o2; o2 = NULL; printf("Primary thread terminating.\n"); return 0; }标签:很赞哦!
