本文实例讲述了C++中Semaphore内核对象的用法，分享给大家供大家参考。具体方法如下：

//Semaphore.cpp:定义控制台应用程序的入口点。 

// 

 

#include"stdafx.h" 

#include<Windows.h> 

#include<process.h>  

 

HANDLEg_hSemaphore; 

DWORDg_nConut1=0; 

DWORDg_nConut2=0; 

unsigned__stdcallThreadProc1(void*pArguments) 

{ 

   ::WaitForSingleObject(g_hSemaphore,INFINITE); 

   for(inti=0;i<10000;i++) 

   { 

       g_nConut1++; 

       g_nConut2++; 

   } 

   ::ReleaseSemaphore(g_hSemaphore,1,NULL); 

   printf("ThreadProc1\n"); 

   return0; 

} 

 

unsigned__stdcallThreadProc2(void*pArguments) 

{ 

   ::WaitForSingleObject(g_hSemaphore,INFINITE); 

   for(inti=0;i<10000;i++) 

   { 

       g_nConut1++; 

       g_nConut2++; 

   } 

   ::ReleaseSemaphore(g_hSemaphore,1,NULL); 

   printf("ThreadProc2\n"); 

   return0; 

} 

 

unsigned__stdcallThreadProc3(void*pArguments) 

{ 

   ::WaitForSingleObject(g_hSemaphore,INFINITE); 

   for(inti=0;i<10000;i++) 

   { 

       g_nConut1++; 

       g_nConut2++; 

   } 

   ::ReleaseSemaphore(g_hSemaphore,1,NULL); 

   printf("ThreadProc3\n"); 

   return0; 

} 

int_tmain(intargc,_TCHAR*argv[]) 

{ 

   g_hSemaphore=::CreateSemaphore(NULL,2,2,NULL); 

   HANDLEhThread[3]; 

   hThread[0]=(HANDLE)::_beginthreadex(NULL,0,ThreadProc1,NULL,0,NULL); 

   hThread[1]=(HANDLE)::_beginthreadex(NULL,0,ThreadProc2,NULL,0,NULL); 

   hThread[2]=(HANDLE)::_beginthreadex(NULL,0,ThreadProc3,NULL,0,NULL); 

 

   ::WaitForMultipleObjects(2,hThread,TRUE,INFINITE); 

   printf("g_count1=%d\n",g_nConut1); 

   printf("g_count2=%d\n",g_nConut2); 

   printf("mainfinished.\n"); 

   return0; 

}

希望本文所述对大家的C++程序设计有所帮助。
