Macro Definition Documentation

ROHC_FEEDBACK_OPT_ACKNUMBER_NOT_VALID

#define ROHC_FEEDBACK_OPT_ACKNUMBER_NOT_VALID   ROHC_FEEDBACK_OPT_SN_NOT_VALID

The Feedback ACKNUMBER-NOT-VALID option (ROHCv2 profiles)

ROHC_FEEDBACK_OPT_MAX_OCCURS

#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.

ROHC_FEEDBACK_OPT_MSN

#define ROHC_FEEDBACK_OPT_MSN   ROHC_FEEDBACK_OPT_SN

The Feedback MSN option (TCP profile)

ROHC_FEEDBACK_OPT_MSN_NOT_VALID

#define ROHC_FEEDBACK_OPT_MSN_NOT_VALID   ROHC_FEEDBACK_OPT_SN_NOT_VALID

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

Enumeration Type Documentation

rohc_feedback_ack_type

enum rohc_feedback_ack_type

The type of acknowledgement

Enumerator
ROHC_FEEDBACK_ACK	The classical ACKnowledgement
ROHC_FEEDBACK_NACK	The Negative ACKnowledgement

rohc_feedback_crc_t

enum rohc_feedback_crc_t

Whether the feedback is protected by a CRC or not.

Enumerator
ROHC_FEEDBACK_WITH_NO_CRC	No CRC protects the feedback
ROHC_FEEDBACK_WITH_CRC_OPT	A CRC option protects the feedback
ROHC_FEEDBACK_WITH_CRC_BASE	A base header CRC protects the feedback

ROHC_FEEDBACK_OPT_CLOCK	The Feedback CLOCK option
ROHC_FEEDBACK_OPT_JITTER	The Feedback JITTER option
ROHC_FEEDBACK_OPT_LOSS	The Feedback LOSS option
ROHC_FEEDBACK_OPT_CV_REQUEST	The Feedback CV-REQUEST option
ROHC_FEEDBACK_OPT_CONTEXT_MEMORY	The Feedback CONTEXT_MEMORY option
ROHC_FEEDBACK_OPT_CLOCK_RESOLUTION	The Feedback CLOCK_RESOLUTION option
ROHC_FEEDBACK_OPT_UNKNOWN_11	Unknown option with value 11
ROHC_FEEDBACK_OPT_UNKNOWN_12	Unknown option with value 12
ROHC_FEEDBACK_OPT_UNKNOWN_13	Unknown option with value 13

rohc_feedback_type

enum rohc_feedback_type

The type of ROHC feedback

Enumerator
ROHC_FEEDBACK_1	ROHC FEEDBACK-1
ROHC_FEEDBACK_2	ROHC FEEDBACK-2
