Detailed Description

Process some YANG validation statements, such as unique-stmt.

The YANG validation is done mostly in the server but some processing such as must, when, and unique are done in the NCX library.

Typedef Documentation

record_unique_error_t

typedef void(* record_unique_error_t) (ses_cb_t *scb, xml_msg_hdr_t *msghdr, val_value_t *errval, dlq_hdr_t *valuniqueQ)

Callback function to generate an rpc_err_rec_t and save it in the msg Use the provided error info record for <rpc-error> fields.

For YANG 'data-not-unique' error-app-tag

Parameters

scb	session control block NULL and no stats will be recorded scb->stats may be updated if scb non-NULL
msghdr	XML msg header with error Q NULL, no errors will be recorded! errQ has error message added if no malloc errors
errval	list value node that contains the unique-stmt
valuniqueQ	Q of val_unique_t structs for error-info

Function Documentation

val_unique_stmt_check()

status_t val_unique_stmt_check	(	ses_cb_t *	scb,
		xml_msg_hdr_t *	msg,
		obj_template_t *	obj,
		val_value_t *	parent,
		val_value_t *	firstval,
		val_value_t *	root,
		record_unique_error_t	error_fn
	)

Check for the proper uniqueness of the tuples within the set of list instances for the specified node.

Parameters

scb	session control block (may be NULL; no session stats)
msg	xml_msg_hdr t from msg in progress NULL MEANS NO RPC-ERRORS ARE RECORDED msg->msg_errQ may have rpc_err_rec_t structs added to it which must be freed by the called with the rpc_err_free_record function
obj	child object of 'parent' that needs the unique test
parent	parent node to search for 'obj' instances
firstval	first instance of 'obj'
root	XPath docroot to use
error_fn	error handler callback for agt; NULL if not used

Returns

status of the operation, NO_ERR if no validation errors found
