Macro Definition Documentation

D_FEEDBACK

#define D_FEEDBACK   (0xf0 >> 3)

The magic bits to find out whether a ROHC packet is a feedback packet

Function Documentation

rohc_feedback_get_size()

bool rohc_feedback_get_size	(	const struct rohc_buf	rohc_data,
		size_t *const	feedback_hdr_len,
		size_t *const	feedback_data_len
	)

Find out the lengths of the feedback header and data.

See 5.2.2 in the RFC 3095 for details.

Parameters

	rohc_data	The ROHC data to get feedback lengths from
[out]	feedback_hdr_len	The length of the feedback header (in bytes)
[out]	feedback_data_len	The length of the feedback data (in bytes)

Returns

true if feedback parsing was successful, false if feedback is malformed

rohc_packet_is_feedback()

bool rohc_packet_is_feedback

(

const uint8_t

byte

)

Find out whether a ROHC packet is a Feedback packet or not.

Parameters

byte	The first byte of ROHC packet to analyze

Returns

Whether the ROHC packet is a Feedback packet or not
