Function Documentation

rohc_decomp_list_create_item()

bool rohc_decomp_list_create_item	(	struct list_decomp *const	decomp,
		const unsigned int	xi_index,
		const unsigned int	xi_index_value,
		const uint8_t *const	rohc_packet,
		const size_t	rohc_max_len,
		size_t *const	item_length
	)

Create a list item from a XI item.

Parameters

	decomp	The context for list decompression
	xi_index	The XI index
	xi_index_value	The XI index value
	rohc_packet	The beginning of the XI item in the ROHC header
	rohc_max_len	The remaining length (in bytes) of the ROHC header
[out]	item_length	The length (in bytes) of the created item

Returns

true if item was successfully created, false if a problem occurred

rohc_list_decode_maybe()

int rohc_list_decode_maybe	(	struct list_decomp *	decomp,
		const uint8_t *	packet,
		size_t	packet_len
	)

Decompress the compressed list in given packet if present.

Parameters

decomp	The list decompressor
packet	The ROHC packet to decompress
packet_len	The remaining length of the packet to decode (in bytes)

Returns

The size of the compressed list in packet in case of success, -1 in case of failure
