objective c - set data filter using "struct sflt_filter" for both TCP and UDP protocol -


मैंने struct sflt_filter का उपयोग किया है जो कि kpi_socketfilter.h का हिस्सा है , व्यक्तिगत रूप से या तो टीसीपी या यूडीपी प्रोटोकॉल के लिए फिल्टर सेट करने के लिए जो ठीक काम कर रहा है।

लेकिन मैं इसे एक ही कार्यक्रम में दोनों टीसीपी और यूडीपी प्रोटोकॉल फिल्टर के लिए चाहता हूं।

यह लाइन काम करती है व्यक्तिगत कॉल - <पूर्व> sflt_register (& amp; sflt_filter_variable, PF_INET, SOCK_STREAM, IPPROTO_TCP);

, PF_INET, SOCK_STREAM, IPPROTO_TCP); sflt_register (& amp; sflt_filter_variable, PF_INET, SOCK_DGRAM, IPPROTO_UDP);

  • एक और चर बनाने "Struct sflt_filter" और इसे इसके बाद के संस्करण के रूप में अलग से दर्ज किया गया है।

    तो मैं दोनों टीसीपी और यूडीपी के लिए फ़िल्टर कैसे रजिस्टर कर सकता हूं।

    जवाब मिल गया,

    sflt_filter_variable.sf_handle चर मान को अन्य 32 बिट अद्वितीय मान में परिवर्तित करना है। 

      sflt_register (& amp; sflt_filter_variable, PF_INET, SOCK_STREAM, IPPROTO_TCP); Sflt_filter_variable.sf_handle = 0x7a5a5f5d; // ** sf_handle का मूल्य बदला। ** sflt_register (& amp; sflt_filter_variable, PF_INET, SOCK_DGRAM, IPPROTO_UDP);   
      
     या अब आप अपने खुद के मूल्यों का उपयोग कर सकते हैं।

    Java - Error: no suitable method found for add(int, java.lang.String) -

    I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

    c++ - static template member variable has internal linkage but is not defined -

    Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
