Thread: Help with OO instrument setup

I'm working on making a class for an instrument I'm working with. This is done with a driver from the vendor.

Once I get the class done I will work on making some sort of GUI to see if my commands are working and setting the instrument as I want.

Am I on the right track? I think I define my own types in case I want to change the return types easily, error types, etc.

Code:

#pragma once#include <string>


class InstrumentX
{
public:
	InstrumentX();
	~InstrumentX();
	long NA_Init(std::string rscr);
	long NA_Close();
	long NA_ErrorQuery(long *errorCode, std::string errorMessage);


private:
	unsigned long handle;
};

Code:

#include "InstrumentX.h"#include "IXdriver.h"
#include <IviVisaType.h>


InstrumentX::InstrumentX()
{
}


InstrumentX::~InstrumentX()
{
}


long InstrumentX::NA_Init(std::string rscr)
{
	long status;
	
	status = IX_InitWithOptions(const_cast<char *>(rscr.c_str()), VI_TRUE, VI_TRUE, "", &handle);
	
	return status;
}


long InstrumentX::NA_Close()
{
	long status;
	
	status = IX_close(handle);


	return status;
}


long InstrumentX::NA_ErrorQuery(long *errorCode, std::string errorMessage)
{
	long status;
	char* temp = nullptr;
	
	status = IX_error_query(handle, errorCode, temp);


	errorMessage = temp;


	return status;
}
