3. Config auswerten

Config auswerten

  • T

    Habe ein kleine funktion geschrieben:

    /*Written by Jan Koester realease under lgpl*/
#include <iostream> 
#include <fstream> 
#include <string> 
#include "easyc++.h"

using namespace std; 

string readconf(char* filename, string confkey)
{ 

        ifstream  file(filename); 
        string buf, key; 
        size_t n; 

        while(file.good()) { 
                getline(file, buf, '\n'); 
                n=buf.find(confkey); 
                if(n != string::npos) { 
                        n += confkey.length();
                        key=buf.substr(n,buf.length()); 
                        break; 
                } else { 
                        continue; 
                } 
        } 

file.close();
        if(key.length() > 0) { 
                return key;
        } else { 
                return "error key not found";
        }

}

    Welche anhand eines Keywords Parameter auslesen kann nun möchte ich nicht jedes mal die Datei auslesen sondern in den Arbeitsspeicher auslagern und global von meinem Modulen drauf zugreifen können, die sich in verschiedenen Klassen sich befinden, die Module werden mit dlopen geladen.

    Hallo

    Glaubst du wirklich das sich jemand deine 100e Zeilen Code anschaut ohne auch nur zu wissen was das Problem ist? "Klappt nicht" ist keine ausreichende Fehlerbeschreibung! 🙄
