Function Documentation

static bool cmp_ipv6_ext	(	const struct rohc_list_item *const	item,
		const uint8_t	ext_type,
		const uint8_t *const	ext_data,
		const size_t	ext_len
	)			[static]

Compare two IPv6 items.

Parameters:

	item	The IPv6 item to compare
	ext_type	The IPv6 Next Header type
	ext_data	The IPv6 extension context
	ext_len	The length (in bytes) of the IPv6 extension context

Returns:

true if the two items are equal, false if they are different

static int get_index_ipv6_table	(	const uint8_t	next_header_type,
		const size_t	occur_nr
	)			[static]

Get the index for the given IPv6 extension type.

Handle GRE, Authentication (AH), MINE, and all IPv6 extension headers.

The list of IPv6 extension headers was retrieved from the registry maintained by IANA at: http://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml Remember to update rohc_is_ipv6_opt if you update the list.

Parameters:

	next_header_type	The Next Header type to get an index for
	occur_nr	The number of occurrence of the Extension Header seen so far (current one included)

Returns:

The based table index

void rohc_comp_list_ipv6_free

(

struct list_comp *const

comp

)

Free one context for compressing lists of IPv6 extension headers.

Parameters:

comp

The context to destroy

void rohc_comp_list_ipv6_new	(	struct list_comp *const	comp,
		const size_t	list_trans_nr,
		rohc_trace_callback2_t	trace_cb,
		void *const	trace_cb_priv,
		const int	profile_id
	)

Create one context for compressing lists of IPv6 extension headers.

Parameters:

	comp	The context to create
	list_trans_nr	The number of uncompressed transmissions (L)
	trace_cb	The function to call for printing traces
	trace_cb_priv	An optional private context, may be NULL
	profile_id	The ID of the associated decompression profile
