postgresql - libpq: How to get the error code after a failed PGconn connection -

-

निम्न कोड को देखते हुए। 

  Pgconn * const conn = PQconnectdbParams (कीवर्ड, मान, असत्य); अगर (! Conn || PQstatus (conn)! = CONNECTION_OK) {/ * त्रुटि कोड? * /}

एक असफल कनेक्शन के मामले में त्रुटि कोड को गलत पासवर्ड और सर्वर के बीच अंतर करने में सक्षम होने का एक तरीका है।

(मुझे पता है कि मुझे त्रुटि संदेश मिल सकता है, लेकिन मैं इसके कारण के अनुसार त्रुटि के कारण प्रतिक्रिया करना चाहता हूं)।

धन्यवाद।

कुछ और शोध करने और पोस्टग्रेस डेवलपर्स पूछने के बाद ऐसा लगता है कि वर्तमान में PQconnectdbParam () से त्रुटि कोड प्राप्त करना संभव नहीं है।

यह स्वयं लिपिपीक की कमी है, जो आंतरिक रूप से (जैसे अज्ञात होस्टनाम) का पता लगाता है, त्रुटियों के लिए एसकेलस्टेट त्रुटि कोड को सौंपने का प्रयास नहीं करता है।

यह पोस्टग्रेर्स देव TODO सूची लेकिन यह प्राथमिकता नहीं है।

TL; DR: यदि आप लिपपीक का उपयोग करने जा रहे हैं, तो पाठ त्रुटि संदेश के साथ जीना सीखें (जो भी भाषा में स्थानीयकृत है)।

I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...
