passing variable number of arguments to a function

Hi Experts,
I want to rename a function from the log4c library for my purpose.  So, I want to have
mylog() instead of the log4c_category_log().  How can I achieve this?

void LOG4C_INLINE mylog(log4c_category_t* catName, int priority, const char *format, ...)
{
    log4c_category_log(catName, priority, ??????);
}

Thank you.
