Define Documentation

#define ROHC_FEEDBACK_OPT_MAX_OCCURS   100U

Max occurrences of a feedback option in one feedback packet.

Even if the standard says that some options may be present multiple times, don't allow more than a raisonable occurrences. It allows the library to protect itself against abuses.

#define ROHC_FEEDBACK_OPT_MSN   ROHC_FEEDBACK_OPT_SN

The Feedback MSN option (TCP profile)

#define ROHC_FEEDBACK_OPT_MSN_NOT_VALID   ROHC_FEEDBACK_OPT_SN_NOT_VALID

The Feedback MSN-NOT-VALID option (TCP profile)

Enumeration Type Documentation

enum rohc_feedback_ack_type

The type of acknowledgement

Enumerator:

ROHC_FEEDBACK_ACK	The classical ACKnowledgement
ROHC_FEEDBACK_NACK	The Negative ACKnowledgement
ROHC_FEEDBACK_STATIC_NACK	The Negative STATIC ACKnowledgement
ROHC_FEEDBACK_RESERVED	reserved (MUST NOT be used for parsability)

enum rohc_feedback_opt

The ROHC feedback options

Enumerator:

ROHC_FEEDBACK_OPT_CRC	The Feedback CRC option
ROHC_FEEDBACK_OPT_REJECT	The Feedback REJECT option
ROHC_FEEDBACK_OPT_SN_NOT_VALID	The Feedback SN-NOT-VALID option

enum rohc_feedback_type

The type of ROHC feedback

Enumerator:

ROHC_FEEDBACK_1	ROHC FEEDBACK-1
ROHC_FEEDBACK_2	ROHC FEEDBACK-2
