Implementation of API to handle Access Rules.

This file contains all methods to handle Access Rule datasets (accessrule_t).

The module consequently uses glib datatypes and api for memory management etc.

gchar* accessrule_as_xml

(

const accessrule_t *

r

)

Create a XML representation of a Access Rule.

Parameters:

r	The Access Rule structure.

Returns:

A newly allocated string with multi-line text. The string needs to be freed with g_free().

Todo:

Use g_markup_escape here

gchar* accessrule_comment

(

const accessrule_t *

r

)

Get the comment string.

Parameters:

r	The Access Rule structure of which the comment should be returned.

Returns:

The comment string. Don't free this.

void accessrule_free

(

accessrule_t *

r

)

Free memory of a access rules structure.

Parameters:

r	The structure to be freed.

gchar* accessrule_ip

(

const accessrule_t *

r

)

Get the IP string.

Parameters:

r	The Access Rule structure of which the IP should be returned.

Returns:

The IP string. Don't free this.

accessrule_t* accessrule_new

(

void

)

Create a new access rule structure filled with the given values.

Returns:

NULL in case the memory could not be allocated. Else an empty accessrule structure which needs to be released using accessrule_free . The whole struct is initalized with 0's.

rule_t accessrule_rule

(

const accessrule_t *

r

)

Get the rule type.

Parameters:

r	The Access Rule structure of which the rule should be returned.

Returns:

The rule type.

int accessrule_set_comment	(	accessrule_t *	r,
		const gchar *	comment
	)

Set the comment of a Access Rule.

Parameters:

r	The Access Rule structure.
comment	The comment string to set. A copy will be created from this.

Returns:

0 for success. Anything else indicates an error.

int accessrule_set_ip	(	accessrule_t *	r,
		const gchar *	ip
	)

Set the IP of a Access Rule.

Parameters:

r	The Access Rule structure.
ip	The IP string to set. A copy will be created from this.

Returns:

0 for success. Anything else indicates an error.

int accessrule_set_oid	(	accessrule_t *	r,
		const rule_t	rule
	)

Set the rule type of a Access Rule.

Parameters:

r	The Access Rule structure.
rule	The rule type to set. A copy will be created from this.

Returns:

0 for success. Anything else indicates an error.

void accessrules_add	(	accessrules_t *	rules,
		accessrule_t *	r
	)

Add an Access Rule to a collection of Access Rules.

Parameters:

rules

The collection of Access Rules (must have ip set).

void accessrules_free

(

accessrules_t *

rules

)

Free a collection of Access Rules.

Parameters:

rules

The collection of Access Rules.

accessrules_t* accessrules_from_file

(

gchar *

fn

)

Read a collection of Access Rules from a file.

Parameters:

fn	The filename from which to read.

Returns:

NULL in case an error occured. Else a collection of access rules which might be empty e.g. if the format was incorrect.

Todo:

Create a access_rules_t* and pass as user data

Todo:

error checks, handling

guint accessrules_size

(

accessrules_t *

rules

)

Get the size of a collection of Access Rules.

Returns:

The number of entries in the collection.

guint accessrules_to_file	(	accessrules_t *	rules,
		gchar *	fn
	)

Write the contents of a Access Rules collection to a file.

Parameters:

rules	The collection of Access Rules.
fn	The filename where to store the Access Rules.
