Segmentation fault on string assignment in C++ -


इस उदाहरण फ़ंक्शन पर एक नज़र डालें: 

  रनटाइम कॉन्फ़िगरेशन * conf_rt_conf () {रनटाइम कॉन्फ़िगरेशन * conf; Conf = नया रनटाइम कॉन्फ़िगरेशन (); conf- & gt; arch_path = "./ संग्रह"; conf- & gt; err_log = "./ err_log"; conf- & gt; fail_log = "./ fail_log"; conf- & gt; msg_log = "./ msg_log"; Conf- & gt; सहेजें = "html, htm, php"; Conf- & gt; अनदेखा = "जेपीजी, जीआईएफ"; conf- & gt; कुकीज़ = ""; वापसी Conf; }

सब कुछ ठीक काम करता है, लेकिन जब मैं इस तरह से कुछ चलाता हूं: 

  DatabaseInput ** conf_db_input () {DatabaseInput ** db_input; Db_input = (डेटाबेसइनपुट **) malloc (NUMB_SITES * sizeof (DatabaseInput *)); (इंट आई = 0; आई & lt; NUMB_SITES; i ++) के लिए db_input [0] = नया डाटाबेसइनपुट (); db_input [0] - & gt; FULL_NAME = "ABCNews"; db_input [0] - & gt; उर्फ ​​= "abcn"; db_input [0] - & gt; उपसर्ग = "/ eng"; db_input [1] - & gt; FULL_NAME = "Rzeczpospolita"; db_input [1] - & gt; उर्फ ​​= "आरपी"; db_input [1] - & gt; उपसर्ग = "/ पोल"; वापसी db_input; }

मुझे पहले असाइनमेंट पर विभाजन त्रुटि मिली। संभवत: इस संरचना के लिए आवंटित निश्चित स्मृति ब्लॉक के साथ कुछ करना है मैं इसे ठीक से काम करने के लिए कैसे दूं?

शायद यह: 

  डेटाबेस इनपुट * db_input []; Db_input = नया डाटाबेसइनपुट * [NUMB_SITES]; // (इंट I = 0; i & lt; NUMB_SITES; i ++) के लिए पॉइंटर्स की एक सरणी बनाता है db_input [i] = नया डाटाबेसइनपुट ();

काम कर सकता है? (मैंने इसका परीक्षण नहीं किया)

ध्यान दें, उपयोग किए जाने वाली मेमोरी को मुक्त करने के लिए, आपको ऐसा कुछ करना चाहिए: 

  के लिए (int i = 0; i & lt; NUMB_SITES; I ++) हटाएं डीबी_इनपुट [आई]; हटाएं [] db_input;

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
