LIBYANG_API_DECL LY_ERR lyplg_ext_schema_mount_create_context	(	const struct lysc_ext_instance *	ext,
		const struct lyd_node *	parent,
		struct ly_ctx **	ctx
	)

	)

Create a shared schema mount context for a schema mount point.

Does nothing if the mount point is not shared or if the context already exists.

For printed contexts (read-only), all shared contexts must be created beforehand by calling this function as they cannot be created once the context is printed.

Parameters

[in]	ext	Compiled extension instance of a schema mount point.
[in]	ext_data	ietf-yang-schema-mount and ietf-yang-library YANG data for the `ext` mount point.

LIBYANG_API_DECL void lyplg_ext_schema_mount_destroy_inline_contexts ( struct lysc_ext_instance * ext )

Destroy all the inline contexts for a given libyang context.

For standard contexts this is done automatically when the context is destroyed. Useful when using a long-lived libyang context for cleaning up memory after completing operations with schema mount extension data that require inline contexts.

Inline contexts are currently not supported in printed contexts.

Parameters

[in] ext Compiled extension instance of a schema mount point. All the inline schema mount contexts that belong to the same libyang context as ext will be destroyed.

LIBYANG_API_DECL void lyplg_ext_schema_mount_destroy_shared_contexts ( struct lysc_ext_instance * ext )

Destroy all the shared schema mount contexts for a given libyang context.

For standard contexts this is done automatically when the context is destroyed.

For printed contexts (read-only), all shared contexts must be destroyed by calling this function as otherwise they will be lost once the original context is destroyed.

Parameters

[in] ext Compiled extension instance of a schema mount point. All the shared schema mount contexts that belong to the same libyang context as ext will be destroyed.

LIBYANG_API_DECL LY_ERR lyplg_ext_schema_mount_get_parent_ref	(	const struct lysc_ext_instance *	ext,
		const struct lyd_node *	parent,
		struct ly_set **	refs
	)

Parameters

[in]	ext	Context allocated for extension.
[in]	parent	Data parent node instance of a schema node with `ext` instance.
[out]	refs	Set of schema node matching parent-reference XPaths.

Returns: LY_ERR value.

LIBYANG_API_DECL LY_ERR lyplg_ext_set_parent_ctx	(	struct ly_ctx *	ctx,
		const struct ly_ctx *	parent_ctx
	)

Set parent context of a context. Errors and callbacks of the parent context will then always be used.

Parameters

[in]	ctx	Context to change.
[in]	parent_ctx	Parent context to set.

Returns: LY_SUCCESS on success.; LY_ERR on error.

LIBYANG_API_DECL const char* lyplg_ext_stmt2str ( enum ly_stmt stmt )

Stringify statement identifier.

Parameters

[in] stmt The statement identifier to stringify.

Returns: Constant string representation of the given stmt.
