Typedef Documentation

◆ rohc_trace_callback2_t

typedef void(* rohc_trace_callback2_t) (void *const priv_ctxt, const rohc_trace_level_t level, const rohc_trace_entity_t entity, const int profile, const char *const format,...)

The function prototype for the trace callback.

User-defined function that is called by the ROHC library every time it wants to print something, from errors to debug. User may thus decide what traces are interesting (filter on level, source entity, or profile) and what to do with them (print on console, storage in file, syslog...).

The user-defined function is set by calling:

function rohc_comp_set_traces_cb2 for a ROHC compressor,
function rohc_decomp_set_traces_cb2 for a ROHC decompressor.

Both functions accept the NULL value to fully disable tracing.

Parameters

priv_ctxt	An optional private context, may be NULL
level	The level of the message,

See also: rohc_trace_level_t

Parameters

entity The entity concerned by the traces

See also: rohc_trace_entity_t

Parameters

profile	The number of the profile concerned by the message
format	The format string for the trace message

See also: rohc_trace_level_t; rohc_trace_entity_t; rohc_comp_set_traces2_cb; rohc_decomp_set_traces2_cb

Enumeration Type Documentation

◆ rohc_cid_type_t

enum rohc_cid_type_t

The different types of Context IDs (CID)

The different types of Context IDs (CID) a ROHC compressor or a ROHC decompressor may use.

Possible values are:

ROHC_LARGE_CID : large CID means that a ROHC compressor or a ROHC decompressor may identify contexts with IDs in the range [0, ROHC_LARGE_CID_MAX ], ie. it may uniquely identify at most ROHC_LARGE_CID_MAX + 1 streams.
ROHC_SMALL_CID : small CID means that a ROHC compressor or a ROHC decompressor may identify contexts with IDs in the range [0, ROHC_SMALL_CID_MAX ], ie. it may uniquely identify at most ROHC_SMALL_CID_MAX + 1 streams.

In short, you choose the CID type in function of the number of simultaneous streams you have to compress efficiently.
