Functions
gchar *	make_table_driven_lsc_info_json_str (const char *, const char *, const char *, const char *, const char *)
	Build a json object with data necessary to start a table drive LSC.
gchar *	get_status_of_table_driven_lsc_from_json (const char *, const char *, const char *, int)
	Get the status of table driven lsc from json object.

Function Documentation

get_status_of_table_driven_lsc_from_json()

gchar * get_status_of_table_driven_lsc_from_json	(	const char *	scan_id,
		const char *	host_ip,
		const char *	json,
		int	len
	)

Get the status of table driven lsc from json object.

Checks for the corresponding status inside the JSON. If the status does not belong the the scan or host, NULL is returned instead. NULL is also returned if message JSON cannot be parsed correctly. Return value has to be freed by caller.

Parameters

scan_id	id of scan
host_ip	ip of host
json	json to get information from
len	length of json

Returns

gchar* Status of table driven lsc or NULL

make_table_driven_lsc_info_json_str()

gchar * make_table_driven_lsc_info_json_str	(	const char *	scan_id,
		const char *	ip_str,
		const char *	hostname,
		const char *	os_release,
		const char *	package_list
	)

Build a json object with data necessary to start a table drive LSC.

JSON result consists of scan_id, message type, host ip, hostname, port together with proto, OID, result message and uri.

Parameters

scan_id	Scan Id.
ip_str	IP string of host.
hostname	Name of host.
os_release	OS release
package_list	The installed package list in the target system to be evaluated

Returns

JSON string on success. Must be freed by caller. NULL on error.
