Function Documentation

refda_eval_condition()

int refda_eval_condition	(	refda_runctx_t *	runctx,
		cace_ari_t *	result,
		const cace_ari_t *	condition
	)

Evaluate given conditional ARI expression and return a boolean ARI indicating whether the condition was true or false.

Parameters

[in]	runctx	The run context.
[out]	result	The single result value from the evaluation. This ARI must be initialized before the call and will be valid if the return code is zero but must be deinitialized regardless.
[in]	condition	The ARI to dereference, if necessary, and evaluate.

Returns

Zero if successful.

refda_eval_target()

int refda_eval_target	(	refda_runctx_t *	runctx,
		cace_ari_t *	result,
		const cace_ari_t *	ari
	)

Implement the evaluation procedure from Section TBD of [ietf-dtn-amm-01].

Parameters

[in]	agent	The agent state for ARI lookup.
[out]	result	The single result value from the evaluation. This ARI must be initialized before the call and will be valid if the return code is zero but must be deinitialized regardless.
[in]	ari	The ARI to dereference, if necessary, and evaluate.

Returns

Zero if successful.
