DESCRIPTION

The X509_POLICY_LEVEL object represents one level of such a tree, corresponding to one certificate.

The X509_POLICY_NODE object represents one node in the tree.

RETURN VALUES

X509_policy_tree_get0_level() returns an internal pointer to the level of the tree with the given index or NULL if the tree argument is NULL or the index is less than 0 or greater than or equal to the number of levels in the tree. An index of 0 corresponds to the trust anchor and the last level corresponds to the target certificate.

X509_policy_level_node_count() returns the number of nodes on the level, including an anyPolicy node if it is present, or 0 if the level argument is NULL.

X509_policy_level_get0_node() returns an internal pointer to the node on the level with the given index or NULL if the level argument is NULL or the index is less than 0 or greater than or equal to the number of nodes on the level. If an anyPolicy node is present on the level, it can be retrieved by passing an index of 0.

X509_policy_node_get0_policy() returns an internal pointer to the valid_policy child object of the node or NULL if the node argument is NULL. It represents a single policy that is valid for the path from the trust anchor to the certificate corresponding to the level containing the node.

X509_policy_node_get0_qualifiers() returns an internal pointer to the qualifier_set child object of the node or NULL if the node argument is NULL. It contains the policy qualifiers associated with the valid_policy of the node in the certificate corresponding to the level containing the node.

X509_policy_node_get0_parent() returns NULL if the node argument is NULL or located on level 0. Otherwise, it returns an an internal pointer to the parent node of the node argument. The parent node is always located on the previous level.
