Issue #4: Placeholder for locator information What kind of data structure should we use to store locator information ? Locator could be either IPv4 or IPv6 address. Required changes should be minimized. Case-1: Locator information to be handled by getsockopt() and setsockopt() Could be one or more locator information. Probably defining a specific data structure would be the right choice. Case-2: Locator information to be included in ancillary data for sendmsg() and recvmsg() A control message (cmsg{}) may contain a single locator information. sockaddr{} would do the job. |
