Define Documentation

#define rc_list_debug	(	comp_list,
		format,
		...		)

Value:

rohc_debug(comp_list, ROHC_TRACE_COMP, (comp_list)->profile_id, \
                   format, ##__VA_ARGS__)

Print a debug trace for the given compression list

Function Documentation

bool detect_ipv6_ext_changes	(	struct list_comp *const	comp,
		const struct ip_packet *const	ip,
		bool *const	list_struct_changed,
		bool *const	list_content_changed
	)

Detect changes within the list of IPv6 extension headers.

Parameters:

	comp	The list compressor
	ip	The IP packet to compress
[out]	list_struct_changed	Whether the structure of the list changed
[out]	list_content_changed	Whether the content of the list changed

Returns:

true if no error occurred, false if one error occurred

int rohc_list_encode	(	struct list_comp *const	comp,
		uint8_t *const	dest,
		int	counter
	)

Generic encoding of compressed list.

Parameters:

	comp	The list compressor
	dest	The ROHC packet under build
	counter	The current position in the rohc-packet-under-build buffer

Returns:

The new position in the rohc-packet-under-build buffer, -1 in case of error

void rohc_list_update_context

(

struct list_comp *const

comp

)

Update the list compression context.

Update the counter of the current list. Update the counters of the items of the current list. Update the reference list with the current list if possible.

Parameters:

comp

The list compressor
