Logger Class in C++

Hi! I am trying to implement a logger class that behaves like printf: this is the only requirement, to implement a member function that accepts a format and a variable number of arguments, just like printf.

However, the static member Logger::log is implemented using old-style C streams:

Code:

void Logger::log(char *format, ...)
{

#ifdef DEBUG
    va_list args;
    char    *p;
    
    // Check for null argument list
    va_start(args, format);    
    p = va_arg(args, char*);

    va_end(args);
    
        //
    va_start(args, format);
    if (p == NULL)
    {

        fprintf(logger, "%s", format);
    }
    else
    {
        fvprintf(logger, format, args);

    }
    
    va_end(args);
#endif
}

My question is simple. Is there a way of moving away the FILE* logger, replacing it with some C++ iostream-reletated class?

Sorry for this (probably) simple question!


Thanks and Cheers!
