Detailed Description

NETCONF Remote Procedure Call Support.

Uses the rpc_msg_t struct and other support from the ncxlib.

Typedef Documentation

◆ agt_rpc_data_cb_t

typedef status_t(* agt_rpc_data_cb_t) (ses_cb_t *scb, rpc_msg_t *msg, uint32 indent)

Callback template for RPCs that use an inline callback function instead of generating a malloced val_value_t tree.

Parameters

scb	session control block
msg	RPC request in progress
indent	start indent amount; ignored if the server is configured not to use PDU indentation

Returns: status of the output operation

◆ agt_rpc_method_t

typedef status_t(* agt_rpc_method_t) (ses_cb_t *scb, rpc_msg_t *msg, xml_node_t *methnode)

Template for RPC server callbacks.

The same template is used for all RPC callback phases The callback is expected to validate if needed and then invoke if needed.

Parameters

scb	session invoking the RPC
msg	message in progress for this <rpc> request the msg->rpc_input value node contains the input (if any). It is a container matching the rpc/input node for the YANG rpc
methnode	XML node for the operation, which can be used in error reporting (or ignored)

Returns

return status for the phase

An error in validate phase will cancel invoke phase
An rpc-error will be added if an error is returned and the msg error Q is empty

Enumeration Type Documentation

◆ agt_rpc_phase_t

enum agt_rpc_phase_t

There are 3 different callbacks possible in the server processing chain.

Only AGT_RPC_PH_INVOKE is needed to do any work Validate is needed if parameter checking beyond the YANG constraints, such as checking if a needed lock is available

The engine will check for optional callbacks during RPC processing.

Enumerator
AGT_RPC_PH_VALIDATE	(2) cb after the input is parsed
AGT_RPC_PH_INVOKE	(3) cb to invoke the requested method
AGT_RPC_PH_POST_REPLY	(5) cb after the reply is generated
AGT_RPC_PH_PARSE	(1) NO CB FOR THIS STATE
AGT_RPC_PH_REPLY	(4) NO CB FOR THIS STATE
