Detailed Description

Interface to Common Platform Enumeration (CPE) Language.

Function Documentation

cpe_lang_export()

void cpe_lang_export	(	const struct cpe_lang_model *	spec,
		xmlTextWriterPtr	writer )

Function for export CPE language top element.

Parameters

writer	xmlTextWriterPtr structure representing XML model
spec	CPE language model structure

cpe_lang_model_export_xml()

void cpe_lang_model_export_xml	(	const struct cpe_lang_model *	spec,
		const char *	file )

Function for export CPE language model to XML.

Parameters

spec	CPE language model structure
file	filename

cpe_lang_model_get_origin_file()

const char * cpe_lang_model_get_origin_file

(

const struct cpe_lang_model *

lang_model

)

Gets the file the CPE dict model was loaded from This is necessary to figure out the full OVAL file path for applicability testing.

We can't do applicability here in the CPE module because that would create awful interdependencies.

cpe_lang_model_parse()

struct cpe_lang_model * cpe_lang_model_parse

(

xmlTextReaderPtr

reader

)

Parse function for CPE Lang model.

Parameters

reader

xmlTextReaderPtr structure representing XML model

cpe_lang_model_set_origin_file()

bool cpe_lang_model_set_origin_file	(	struct cpe_lang_model *	lang_model,
		const char *	origin_file )

Sets the origin file hint.

platform	CPE platform structure

cpe_platform_parse()

struct cpe_platform * cpe_platform_parse

(

xmlTextReaderPtr

reader

)

Parse CPE platform structure.

Parameters
