Parameters

[out]	stack	to populate.
[in]	da	to build the stack for.

fr_proto_next_encodable()

void* fr_proto_next_encodable	(	fr_dlist_head_t *	list,
		void *	current,
		void *	uctx
	)

Implements the default iterator to encode pairs belonging to a specific dictionary that are not internal.

Parameters

[in]	list	to iterate over.
[in]	current	The fr_pair_t cursor->current. Will be advanced and checked to see if it matches the specified fr_dict_t.
[in]	uctx	The fr_dict_t to search for.

Returns

• Next matching fr_pair_t.
• NULL if not more matching fr_pair_ts could be found.
