map_proc()

unlang_action_t map_proc	(	rlm_rcode_t *	p_result,
		request_t *	request,
		map_proc_inst_t const *	inst,
		fr_value_box_list_t *	result
	)

Evaluate a set of maps using the specified map processor.

Evaluate the map processor src template, then call a map processor function to do something with the expanded src template and map the result to attributes in the request.

Parameters

[out]	p_result	Result code of evaluating the map.
[in]	request	The current request.
[in]	inst	of a map processor.
[in,out]	result	Result of expanding the map input. May be consumed by the map processor.

Returns

one of UNLANG_ACTION_*

map_proc_cmp()

static int8_t map_proc_cmp ( void const *  one, void const *  two  )

static

Compare two map_proc_t structs, based ONLY on the name.

Parameters

[in]	one	First map struct.
[in]	two	Second map struct.

Returns

Integer specifying order of map func instances.

map_proc_find()

map_proc_t* map_proc_find

(

Parameters

[in]

name

Returns

• map_proc matching name.
• NULL if none was found.

		map_proc_t const *	proc,
		CONF_SECTION *	cs,
		tmpl_t const *	src,
		map_list_t const *	maps
	)

Create a new map proc instance.

This should be called for every map {} section in the configuration.

Parameters

[in]	ctx	to allocate proc instance in.
[in]	proc	resolved with map_proc_find.
[in]	cs	CONF_SECTION representing this instance of a map processor.
[in]	src	template.
[in]	maps	Head of the list of maps.

Returns

• New map_proc_inst_t on success.
• NULL on error.

		map_proc_func_t	evaluate,
		map_proc_instantiate_t	instantiate,
		size_t	inst_size,
		fr_value_box_safe_for_t	literals_safe_for
	)

Register a map processor.

This should be called by every module that provides a map processing function.

Parameters

[in]	ctx	if non-null, the ctx to bind this map processor to.
[in]	mod_inst	of module registering the map_proc.
[in]	name	of map processor. If processor already exists, it is replaced.
[in]	evaluate	Module's map processor function.
[in]	instantiate	function (optional).
[in]	inst_size	of talloc chunk to allocate for instance data (optional).
[in]	literals_safe_for	What safe_for value to assign to literals.

Returns

• 0 on success.
• -1 on failure.
