服务器端：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])<br /> {<br /> printf("==========这里是服务器端==========/r/n");<br /> //获取标准输入、输出句柄<br /> HANDLE hStdIn = ::GetStdHandle(STD_INPUT_HANDLE);<br /> HANDLE hStdOut = ::GetStdHandle(STD_OUTPUT_HANDLE);<br /> DWORD dwRead = 0;<br /> //从标准输入中读取参数<br /> int args[2];<br /> ReadFile(hStdIn, args, sizeof(args), &dwRead, NULL);<br /> if(dwRead > 0)<br /> {<br /> //加法计算<br /> int a = args[0];<br /> int b = args[1];<br /> int c = Plus(a,b);<br /> DWORD dwWrite = 0;<br /> WriteFile(hStdOut, &c, sizeof(c), &dwWrite, NULL);<br /> }<br /> return 0;<br /> } 

客户端：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])<br /> {<br /> printf("==========这里是客户端==========/r/n");<br /> HANDLE hChildStdInRead, hChildStdInWrite;<br /> HANDLE hChildStdOutRead, hChildStdOutWrite;<br /> //安全属性<br /> SECURITY_ATTRIBUTES sa;<br /> sa.nLength = sizeof(SECURITY_ATTRIBUTES);<br /> sa.bInheritHandle = TRUE; //子进程可以继承父进程创建管道的读写句柄<br /> sa.lpSecurityDescriptor = NULL;<br /> //创建标准输入管道<br /> if (!CreatePipe(&hChildStdInRead, &hChildStdInWrite, &sa, 0))<br /> {<br /> printf("Create inPipe failed!/r/n");<br /> return -1;<br /> }<br /> //创建标准输出管道<br /> if (!CreatePipe(&hChildStdOutRead, &hChildStdOutWrite, &sa, 0))<br /> {<br /> printf("Create outPipe failed!/r/n");<br /> return -1;<br /> }<br /> //进程属性<br /> PROCESS_INFORMATION pi;<br /> STARTUPINFO si = { sizeof(si) };<br /> si.wShowWindow = SW_HIDE;<br /> si.hStdInput = hChildStdInRead;<br /> si.hStdOutput = hChildStdOutWrite;<br /> si.hStdError = GetStdHandle(STD_ERROR_HANDLE);<br /> si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;<br /> //使用显示窗口和标准句柄的标志<br /> TCHAR cCommandLine[_MAX_PATH] = _T("PipeServer.exe");<br /> //启动PipeServer.exe<br /> if (CreateProcess(NULL, cCommandLine, NULL, NULL, TRUE, 0, NULL, NULL, &si, π))<br /> {<br /> CloseHandle(pi.hProcess);<br /> CloseHandle(pi.hThread);<br /> DWORD dwWrite = 0;<br /> int args[] = {16, 26};</p> <p> //发送参数值<br /> WriteFile(hChildStdInWrite, args, sizeof(args), &dwWrite, NULL);<br /> printf("客户端正写入管道的参数：(%d, %d)/r/n", args[0], args[1]);<br /> DWORD dwRead = 0;<br /> int c = 0;<br /> ReadFile(hChildStdOutRead, &c, sizeof(c), &dwRead, NULL);<br /> printf("客户端读取管道的计算结果：%d + %d = %d/r/n", args[0], args[1], c);<br /> }<br /> return 0;<br /> } 

测试结果：

==========这里是服务器端==========</p> <p>==========这里是客户端==========<br /> 客户端正写入管道的参数：(16, 26)<br /> 客户端读取管道的计算结果：16 + 26 = 42<br /> 请按任意键继续. . .
