Detailed Description

Session Control Block.

Field Documentation

◆ binary_notifs

boolean binary_notifs

Flag to indicate Binary Notification Messages are expected to be received on this session.

This supports the encode-yang-cbor setting for the establish-subscription operation

◆ breadcrumbQ

dlq_hdr_t breadcrumbQ

Queue of breadcrumb object back pointers used in XPath GET2 processing of when-stmts in operational state Contains backptr to obj_template_t to prevent loops.

Q of ncx_backptr_t to obj_template_t

◆ file_override

boolean file_override

set by server DB-API session to capture <rpc-reply> output to a file.

The session FD IO is not changed. During this mode the session output will go to scb->fp instead of scb->fd

◆ reading_header

boolean reading_header

variables for SSL sessions; used by yangcli-pro

T if reading hdr F if reading body

◆ service_name

xmlChar* service_name

variables for ycontrol sessions

type of control session

◆ snmp_getnext_listQ

dlq_hdr_t snmp_getnext_listQ

SNMP pointers Q of malloced val_value struct
Q of list entries with only keys in it.


Used to find the best getnext match.
This Queue is getting saved only if the operation is GETNEXT. So the server can reuse the same Queue if the getnext operation is trying to getnext leaf object on the same TABLE

◆ subsys_id

xmlChar* subsys_id

used for YCONTROL session only

Matches subsystem config

◆ yang_sid_tree

uint32 yang_sid_tree

SID Tree Assignment for this session.

Needed to select the YANG to CBOR mapping set to use

◆ yp_mode

ses_ypmode_t yp_mode

YANG-PATCH mode:

  • RESTCONF
  • NETCONF
  • HA
