使用邮槽传输对象

服务端：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]){printf("=============Mailslot服务端=============/r/n");//创建邮槽HANDLE hMailslot;hMailslot = CreateMailslot(_T("////.//mailslot//MyMailslot"),0,MAILSLOT_WAIT_FOREVER,NULL);if (INVALID_HANDLE_VALUE == hMailslot){printf("CreateMailslot is failed!/r/n");return -1;}printf("按任意键读取客户端写入邮槽的参数.../r/n");_getch();int args[2];DWORD dwRead;ReadFile(hMailslot, args, sizeof(args), &dwRead, NULL);//从客户端读取参数int a, b, c;int *pIntBuf = args;a = *(pIntBuf);pIntBuf++;b = *(pIntBuf);printf("服务端读取到参数(%d, %d)/r/n", a, b);c = a + b;printf("计算结果为：%d/r/n", c);CloseHandle(hMailslot);return 0;} 

 

客户端：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]){printf("=============Mailslot客户端=============/r/n");HANDLE hMailslot;hMailslot = CreateFile(_T("////.//mailslot//MyMailslot"),GENERIC_WRITE | GENERIC_WRITE,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);if (INVALID_HANDLE_VALUE == hMailslot){printf("CreateFile is failed!/r/n");return -1;}printf("按任意键准备从客户端写入邮槽的参数.../r/n");_getch();int args[2] = { 16, 26 };DWORD dwWrite;WriteFile(hMailslot, args, sizeof(args), &dwWrite, NULL);printf("已经写入参数(%d, %d)到邮槽，因为是单向通信，结果需从服务器端查看.../r/n", args[0], args[1]);CloseHandle(hMailslot);return 0;} 

 

测试运行结果：

=============Mailslot服务端=============按任意键读取客户端写入邮槽的参数...服务端读取到参数(16, 26)计算结果为：42请按任意键继续. . .=============Mailslot客户端=============按任意键准备从客户端写入邮槽的参数...已经写入参数(16, 26)到邮槽，因为是单向通信，结果需从服务器端查看...请按任意键继续. . .
