Data Structure Documentation

fr_io_instance_t

struct fr_io_instance_t

The master IO instance.

This structure is the instance data for the "master" IO handler. The structure is exposed for simplicity right now. It may be made private in the future.

The fr_master_io_listen() should be used to create a listener from this structure.

Note that most entries of this structure MUST be initialized before fr_master_io_listen() is called. That function only creates the listener, and adds it to the scheduler.

Data Fields
fr_app_t *	app	main protocol handler
void *	app_instance	instance data for main protocol handler
fr_app_io_t const *	app_io	Easy access to the app_io handle.

fr_master_io_network()

fr_trie_t* fr_master_io_network	(	TALLOC_CTX *	ctx,
		int	af,
		fr_ipaddr_t *	allow,
		fr_ipaddr_t *	deny
	)

Create a trie from arrays of allow / deny IP addresses.

Parameters

ctx	the talloc ctx
af	the address family to allow
allow	the array of IPs / networks to allow. MUST be talloc'd
deny	the array of IPs / networks to deny. MAY be NULL, MUST be talloc'd

Returns

• fr_trie_t on success
• NULL on error
