Detailed Description

Function Documentation

ds_rds_create()

OSCAP_API int ds_rds_create	(	const char *	sds_file,
		const char *	xccdf_result_file,
		const char **	oval_result_files,
		const char *	target_file
	)

takes given source data stream and XCCDF result file and makes a result data stream

Parameters

sds_file	Path to the source data stream file that was used to generate the result XCCDF
xccdf_result_file	Contains xccdf:TestResult(s) and the embedded Benchmark (optionally). The embedded Benchmark (source data) will not be included in the result data stream, we will instead bundle the source data stream.
oval_result_files	NULL terminated list of paths to OVAL result files that should be bundled in the result data stream.
target_file	Path to the file where the result data stream will be stored

Returns

0 if no errors were encountered -1 in case of errors

ds_sds_compose_add_component()

OSCAP_API int ds_sds_compose_add_component	(	const char *	target_datastream,
		const char *	datastream_id,
		const char *	new_component,
		bool	extended
	)

append a new given component to the existing source datastream

Parameters

target_datastream	Path of the existing source datastream into which the new component shall be added.
datastream_id	ID of the datastream into which the component shall be added. Null value indicates the very first datastream in the collection.
new_component	Path to the new component file (XCCDF, OVAL, or CPE Dictionary).

Returns

0 in case of success

ds_sds_compose_from_xccdf()

OSCAP_API int ds_sds_compose_from_xccdf	(	const char *	xccdf_file,
		const char *	target_datastream
	)

takes given xccdf file and constructs a source datastream

Parameters

xccdf_file	Path to the XCCDF file that should be included in the datastream (including its dependencies).
target_datastream	ID of the datastream that should contain the XCCDF file. It will be the only datastream in the resulting data-stream-collection.

Returns

0 if no errors were encountered -1 in case of errors

ds_sds_index_free()

ds_sds_index_select_checklist()

OSCAP_API int ds_sds_index_select_checklist	(	struct ds_sds_index *	s,
		const char **	datastream_id,
		const char **	component_id
	)

chooses datastream and checklist id combination given the IDs

Parameters

datastream_id	has to point to an allocated char*, selected datastream ID will be filled into it
component_id	has to point to an allocated char*, selected xccdf ID will be filled into it

datastream_id and component_id must not point to the same memory! However, the pointers pointed to may be NULL (which means any ID will do).

component_id is actually a component-ref ID, the reason is that we need the component-ref to know which other components are in the catalog and thus needed when splitting.

ds_sds_index_select_checklist_by_benchmark_id()

OSCAP_API int ds_sds_index_select_checklist_by_benchmark_id	(	struct ds_sds_index *	s,
		const char *	benchmark_id,
		const char **	datastream_id,
		const char **	component_ref_id
	)

chooses datastream and checklist component ref ID combination, given benchmark ID

Parameters

benchmark_id

Which XCCDF Benchmark ID are we looking for? Parameters are similar to ds_sds_index_select_checklist, except for benchmark_id.

See also

ds_sds_index_select_checklist

This function looks through to datastream index to find the first component-ref (top-down) which satisfies the following condition: "it does point to a component which contains XCCDF Benchmark with id exactly the same as given benchmark_id".

Please note that datastream_id AND component_ref_id are pointers to pointers and they will be overwritten if 0 is returned. The values are never used, unlike with ds_sds_index_select_checklist.
