/*
 * This function converts the template parameter (option) --xaddr
 * to final URL for the ONVIF service. If this option is specified on the command line
 * does not contain a template parameter %s function snprintf() just make a copy in a static array.
 * If option contains template parameter %s, it will be replaced by
 * IP addres of Network interface specified by --if_name option.
 *
 * Example:
 * ./wsdd --xaddr "http://192.168.1.1:2000/onvif/device_service" - will not be changed
 *
 * ./wsdd --xaddr "http://%s:2000/onvif/device_service" --if_name eth1
 * template %s will be replaced to the IP address of the network interface eth1
