Define Documentation

#define C_NUM_PROFILES   6

The number of ROHC profiles ready to be used

Referenced by rohc_activate_profile(), rohc_alloc_compressor(), rohc_c_info(), and rohc_c_statistics().

#define CHANGE_TO_FO_COUNT   700

The default maximal number of packets sent in > FO states (= SO state) before changing back the state to FO (periodic refreshes)

Referenced by rohc_alloc_compressor().

#define CHANGE_TO_IR_COUNT   1700

The default maximal number of packets sent in > IR states (= FO and SO states) before changing back the state to IR (periodic refreshes)

Referenced by rohc_alloc_compressor().

#define FEEDBACK_RING_SIZE   1000

The maximal number of outgoing feedbacks that can be queued

Referenced by rohc_alloc_compressor(), rohc_comp_piggyback_feedback(), rohc_feedback_remove_locked(), and rohc_feedback_unlock().

#define MAX_FO_COUNT   3

The minimal number of packets that must be sent while in FO state before being able to switch to the SO state

#define MAX_RTP_PORTS   15

The maximal number of RTP ports (shall be > 2)

Referenced by rohc_alloc_compressor(), rohc_comp_add_rtp_port(), rohc_comp_remove_rtp_port(), and rohc_comp_reset_rtp_ports().

#define rohc_comp_debug	(		context,
			format,
			...
	)

Value:

rohc_debug((context)->compressor, ROHC_TRACE_COMP, \
                   (context)->profile->id, \
                   format, ##__VA_ARGS__)
