* 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'.
|
|
*
|
|
* 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.
