2019-06-18api: string type to convert to vectorOle Troan1-0/+1
Previous use of strndup() required user to remember to call free(). Now return a vector pointing directly to the API message string. Of course user must remember to copy the string out if lifetime is longer than API message lifetime.

2019-04-10API: Fix shared memory only action handlers.Ole Troan1-11/+11
Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport. A couple (bond / vhost) also tried to send a sw_interface_event directly, but did not send the message to all that had registred interest. That scheme never worked correctly. Refactored and improved the interface event code. Change-Id: Idb90edfd8703c6ae593b36b4eeb4d3ed7da5c808 Signed-off-by: Ole Troan <ot@cisco.com>
