Function Documentation

rohc_comp_ipv6_exts_are_acceptable()

bool rohc_comp_ipv6_exts_are_acceptable	(	const struct rohc_comp *const	comp,
		uint8_t *const	next_proto,
		const uint8_t *const	exts,
		const size_t	max_exts_len,
		size_t *const	exts_len
	)

Whether IPv6 extension headers are acceptable or not.

IPv6 options are acceptable if:

• the last IPv6 extension header is not truncated,
• no more than ROHC_MAX_IP_EXT_HDRS extension headers are present,
• each extension header is present only once (except Destination that may occur twice).

Parameters

	comp	The ROHC compressor
[in,out]	next_proto	in: the protocol type of the first extension header out: the protocol type of the transport header
	exts	The beginning of the IPv6 extension headers
	max_exts_len	The maximum length (in bytes) of the extension headers
[out]	exts_len	The length (in bytes) of the IPv6 extension headers

Returns

true if the IPv6 extension headers are acceptable, false if they are not
