Function Documentation

int oval_session_evaluate ( struct oval_session session,
char *  probe_root,
agent_reporter  fn,
void *  arg 
)

Evaluate OVAL Definitions.

Optionally you can set a callback function which will be called upon single evaluation. Use oval_result_definition_get_id to get the ID of the evaluated OVAL Definion and oval_result_definition_get_result, oval_result_get_text to get a text representation of the result.

Parameters
sessionan oval_session
probe_rootFIXME:
fna callback function
argan optional argument for your callback function
Return values
0on success
1on an internal error (use oscap_err_desc or oscap_err_get_full_error to get more details)
int oval_session_evaluate_id ( struct oval_session session,
char *  probe_root,
const char *  id,
oval_result_t result 
)

Evaluate a specific OVAL Definition.

The result of the evaluation will be written into the result argument. You can convert it into a string representation with oval_result_get_text.

Parameters
sessionan oval_session
probe_rootFIXME:
idid of an OVAL Definition
resultvariable to write the result into
Return values
0on success
1on an internal error (use oscap_err_desc or oscap_err_get_full_error to get more details)
int oval_session_export ( struct oval_session session)

Export result to a file.

Results can be represented as OVAL System Characteristics if analyse has been done or OVAL Results if evaluation or collect has been done. If there aren't any filenames set or no operation was performed then this function has no effect.

Alse see: oval_session_set_results_export oval_session_set_report_export

Parameters
sessionan oval_session
Return values
0on success
1on an internal error (use oscap_err_desc or oscap_err_get_full_error to get more details)
void oval_session_free ( struct oval_session session)

Destructor of an oval_session.

Parameters
sessionan oval_session to destroy
int oval_session_load ( struct oval_session session)

Load OVAL Definitions and bind OVAL Variables to it if provided.

Validation if performed automatically if you've set it with oval_session_set_validation. if the validation failed then the function will print information about what line in what file isn't valid and why not.

Parameters
sessionan oval_session
Return values
0on success
1on an internal error (use oscap_err_desc or oscap_err_get_full_error to get more details)
struct oval_session * oval_session_new ( const char *  filename)

Costructor of an oval_session.

It attempts to recognize a type of the filename which has to be a source datastream or OVAL Definitions.

Parameters
filenamea path to an OVAL or source datastream file
Returns
a newly created oval_session
Return values
NULLin case of an error (use oscap_err_desc or oscap_err_get_full_error to get more details)
void oval_session_set_component_id ( struct oval_session session,
const char *  id 
)

Set ID of a particular OVAL component if there are two OVALs in one source datastream.

If the ID has been already set then it will be overwritten.

Parameters
sessionan oval_session
idan id of a definition
void oval_session_set_datastream_id ( struct oval_session session,
const char *  id 
)

Set ID of a specific OVAL Definition in an source datastream.

If the ID has been already set then it will be overwritten. In case where there are two OVALs in one datastream use oval_session_set_component_id.

Parameters
sessionan oval_session
idan id of a definition
void oval_session_set_directives ( struct oval_session session,
const char *  filename 
)

Set OVAL Directives.

If a filename has been already set then it will be overwritten. If you pass NULL as filename argument then the currently set variables will be freed. Validation of the format will be perforemed when the oval_session_load is called.

Parameters
sessionan oval_session
filenamea path to an OVAL Directives file
void oval_session_set_export_system_characteristics ( struct oval_session session,
bool  export 
)

Set exporting of system characteristics in OVAL results.

Parameters
sessionan oval_session
exportfalse values indicated no system_characteristics in OVAL Results
void oval_session_set_remote_resources ( struct oval_session session,
bool  allowed,
download_progress_calllback_t  callback 
)

Set property of remote content.

Parameters
sessionan oval_session
allowedWhether is download of remote resources allowed in this session (defaults to false)
callbackused to notify user about download proceeds. This might be safely set to NULL – ignoring user notification.
void oval_session_set_report_export ( struct oval_session session,
const char *  filename 
)

Set a name of the file that the the OVAL Results, converted to HTML format, will be written into.

If the file's name has been already set for the current session then it will be overwritten.

Parameters
sessionan oval_session
filenamea path to a new file
void oval_session_set_results_export ( struct oval_session session,
const char *  filename 
)

Set a name of the file that the the OVAL Results will be written into.

If the file's name has been already set for the current session then it will be overwritten.

Parameters
sessionan oval_session
filenamea path to a new file
void oval_session_set_validation ( struct oval_session session,
bool  validate,
bool  full_validation 
)

Set XSD validation level.

Parameters
sessionan oval_session
validatefalse value indicates to skip any XSD validation
full_validationtrue value indicates that every possible step will be validated by XSD
void oval_session_set_variables ( struct oval_session session,
const char *  filename 
)

Set OVAL Variables.

If a filename has been already set then it will be overwritten. If you pass NULL as filename argument then the currently set variables will be freed. Validation of the format will be perforemed when the oval_session_load is called.

Parameters
sessionan oval_session
filenamea path to an OVAL Variables file
void oval_session_set_xml_reporter ( struct oval_session session,
xml_reporter  fn 
)

Set XML validation reporter.

This function is called when there is something invalid in input/output XML file.

Parameters
sessionan oval_session
fnpointer to XML reporter function
