Output redirection?

[Blender3D]

Hello, Guys

I have a short question again: How can outputs of Irrlicht be redirected to any file (e.g. /dev/null)? I know that you cat do this when you don't call ./yourExectable but ./yourExecutable > /dev/null. But don't want to call my programm from the shell. So this dataredirection should be in the sourcecode.

Many thanks for any usefull answere!!

Do you mean the console output?

This has been discussed before so try searching for it. I know that irrlicht's log events go through the even receiver so if there's no way of telling irrlicht where to put the events automatically you could grab them there and send them elsewhere yourself, then return true so they don't get to the console.

Thanks for replying my post...

I will try to find something with google, the searchengine here etc. (I am so stupid that I didn't searched first)

Hmm, freopen("log.txt", "w", stdout) isn't working. I guess the modified stdout isn't usable from the DLL.

Ah well, here's the 'proper' way to do it.

Code: Select all

class LogReceiver : public IEventReceiver
{
public:
    virtual bool OnEvent(const SEvent & event)
    {
        if(event.EventType == EET_LOG_TEXT_EVENT)
        {
            log(event.LogEvent.Text);
            return true; // Stops the event getting to the Irrlicht log as well
        }
    }

    void log(const char * message)
    {
        fprintf(LogFile, "%s\n", message);
    }

    void openLogFile(const char * filename)
    {
        LogFile = fopen(filename, "w");
    }

    void closeLogFile(void)
    {
        if(LogFile)
        {
            fclose(LogFile);
            LogFile = 0;
        }
    }

    FILE * LogFile;
};

// ... then after you create your device...

    LogReceiver receiver;
    receiver.openLogFile("log.txt");
    device->setEventReceiver(&receiver);
    receiver.log("You can use the same logger for your application logging");

// ... and finally ...

    receiver.closeLogFile();
