Hi all...
can anyone explain how i can read from a config file and retrieve its value in a cpp file...
I am writing down the cfg file...

and the cpp file, in which i need to read it is...
#include "ConfigInterface.h"
CI(string file, string comp) //constructor
{
_file_name = file;
_comp_name = comp;
init();
}
void * CI::getval(string event, string event_data)
{
setresult(event, event_data);
return result ;
}
// processing to read the config file here.
void CI::init()
{
//need to work on.......
}
void CI::setresult(string event, string event_data)
{
// need to work on.......
}
int main()
{
CI MGRConfig("MyConfigData.cfg", "MGR");
// creating object of CI class and providing config file name and //section name i wnat to read.
int *sysMgrTimeOut = (int*)MGRConfig.getval("MGR_SYS", "ResetTimeout");
// i have type casted the value bcoz getval will return void*, in fact //that's why it is returning void*, so that we can convert it in any //type.
cout<<*sysMgrTimeOut;
// Now it should print 200.0 as per the confg file.
// same way it can get read any value from config file for any events //fo any component.
return 0;
}-------------------------------------------------------------------------------
and the header file is:
//ConfigInterface.h
//i can add any function/varibale/member in private section for my //processing.
class CI
{
private:
// the config file i need to read.
string _file_name;
// component i need to read from config file. e.g <XR>string _comp_name
// requested events in getval. e.g [XR_ONE]
string _events;
// requested events_data getval. e.g EventId_0
string _events_data;
// function to set the requested value.
void setval(string event, string event_data);
void * result;
void init();
// in this function i need to do all processing to read the config
//file and set the value for diffrent events data of diffrent //components
public:
CI(string file, string comp); //constructor
void * getval(string event, string event_data);
// should be return void pointer on the value so that it can be //convert into any data type later.
};
