Detailed Description

Network packet (may contains several IP headers)

Typedef Documentation

typedef uint32_t rohc_ctxt_key_t

The key to help identify (not quaranted unique) a compression context

size_t ROHC_EXPORT net_pkt_get_payload_offset ( const struct net_pkt *const packet )

Get the offset of the IP payload in the given packet.

The payload begins after the innermost IP header (and its extension headers).

Parameters:

packet The packet to get the payload offset for

bool ROHC_EXPORT net_pkt_parse	(	struct net_pkt *const	packet,
		const struct rohc_buf	data,
		rohc_trace_callback_t	trace_cb,
		rohc_trace_callback2_t	trace_cb2,
		void *const	trace_cb_priv,
		rohc_trace_entity_t	trace_entity
	)

Parse a network packet.

Parameters:

[out]	packet	The parsed packet
	data	The data to parse
	trace_cb	The old function to call for printing traces
	trace_cb2	The new function to call for printing traces
	trace_cb_priv	An optional private context, may be NULL
	trace_entity	The entity that emits the traces

Returns:: true if the packet was successfully parsed, false if a problem occurred (a malformed packet is not considered as an error)
