Function Documentation

ip4_fib_t* find_ip4_fib_by_table_index_or_id	(	ip4_main_t *	im,
		u32	table_index_or_id,
		u32	flags
	)

Get or create an IPv4 fib.

Get or create an IPv4 fib with the provided fib ID or index. The fib ID is a possibly-sparse user-defined value while the fib index defines the position of the fib in the fib vector.

Parameters

im	ip4_main pointer.
table_index_or_id	The table index if `IP4_ROUTE_FLAG_FIB_INDEX` bit is set in `flags`. Otherwise, when set to `~0`, an arbitrary and unused fib ID is picked and can be retrieved with `ret->table_id`. Otherwise, the fib ID to be used to retrieve or create the desired fib.
flags	Indicates whether `table_index_or_id` is the fib index or ID. When the bit `IP4_ROUTE_FLAG_FIB_INDEX` is set, `table_index_or_id` is considered as the fib index, and the fib ID otherwise.

Returns: A pointer to the retrieved or created fib.

Remarks: When getting a fib with the fib index, the fib MUST already exist.
