Detailed Description

Special UDP-Notif Collector Control Block Used to manage the DGRAM connection where the publishers are not known in advance.

Field Documentation

curmsg_addr

xmlChar curmsg_addr[SES_SOCKADDR_BUFFLEN]

UDP-Notif needs to capture the IP address and port of the UDP packet sender since this can be different for each packet.

• Each time the udpnotif_read function is called the curmsg_addr field is set via 'recvfrom' function.
• Then the publisher CB is found or created in udpnoiif udpnotif_get_msgQ when a message is complete and 'ready' and the curmsg_print_addr is set
• The application layer uses this info via the setup_fn callback to find the YANG library (first time) or setup current session state to the correct YANG library state

struct sockaddr_in curmsg_addr;

pubcbQ

dlq_hdr_t pubcbQ

UDP-Notif needs a special Queue of publisher control blocks since multiple source addresses can be sending to the same collector.

This queue of internal structs in udpnotif is cleaned with udpnotif_clean_scb TEMP : STORE IN QUEUE :: WILL CHANGE TO AVL TREE

setup_fn

ses_setup_fn_t setup_fn

The session control block setup by udpnotif_init is the collector session listening to the collector socket.

Each time a message is received the session setup callback is invoked so the correct YANG modules can be in place to process the incoming message
