how to forward variable number of arguments to another function?
<p>In my application I have a lot of logs. I do accumulate all errors from all logs in one place called <code>errorsLogger</code>. I've implemented it this way:</p>

<pre><code>static Logger errorsLogger;

....

void Logger::Error(std::string format, ...) {
    va_list arglist;
    va_start(arglist, format);

    if (this != &amp;errorsLogger) {
        errorsLogger.Error(format, arglist);      // how to forward parameters?
    }

    vfprintf(logFile, , format.c_str(), arglist);
    fprintf(logFile, "\n");

    fflush(logFile);
    va_end( arglist );
}
</code></pre>

<p>However this code doesn't work as expected <code>errorsLogger</code> contains a little bit strange strings - it seems variable arguments was not passed. How to fix my code to be valid?</p>
