/*! \brief
 * Returns the statistic associated with 'numerical_code' and 'is_a_reply'.
 * Specifically:
 *  - if in_codes is nonzero, then the stat_var for the number of messages 
 *    _received_ with the 'numerical_code' will be returned if it exists.
 *  - otherwise, the stat_var for the number of messages _sent_ with the 
 *    'numerical_code' will be returned, if the stat exists.

 * This function will retrieve a list of all ip addresses and ports that Kamailio
 * is listening on, with respect to the transport protocol specified with
 * 'protocol'. This function only returns IPv4 addresses.
 * The first parameter, ipList, is a pointer to a pointer. It will be assigned a
 * new block of memory holding the IP Addresses and ports being listened to with
 * respect to 'protocol'.  The array maps a 2D array into a 1 dimensional space,
 * and is layed out as follows:
 * The first NUM_IP_OCTETS indices will be the IP address, and the next index
 * the port.  So if NUM_IP_OCTETS is equal to 4 and there are two IP addresses
 * found, then:
 *  - ipList[0] will be the first octet of the first ip address
 *  - ipList[3] will be the last octet of the first ip address.
 *  - iplist[4] will be the port of the first ip address
 *  - 
 *  - iplist[5] will be the first octet of the first ip address, 
 *  - and so on.  
 * The function will return the number of sockets which were found.  This can be
 * used to index into ipList.
 * \note This function assigns a block of memory equal to:
 *            returnedValue * (NUM_IP_OCTETS + 1) * sizeof(int);
 *       Therefore it is CRUCIAL that you free ipList when you are done with its
 *       contents, to avoid a nasty memory leak.

 * Returns the sum of the number of bytes waiting to be consumed on all network
 * interfaces and transports that Kamailio is listening on. 
 * Note: This currently only works on systems supporting the /proc/net/[tcp|udp]
 *       interface.  On other systems, zero will always be returned.  Details of
 *       why this is so can be found in network_stats.c
