Detailed Description

Message traces.

Functions for modules to emit traces.

Macro Definition Documentation

vlc_tracer_Trace

#define vlc_tracer_Trace	(		tracer,
			...
	)		vlc_tracer_TraceWithTs(tracer, vlc_tick_now(), __VA_ARGS__)

Typedef Documentation

vlc_trace_cb

typedef void(* vlc_trace_cb) (void *data, vlc_tick_t ts, va_list entries)

Trace logging callback signature.

va-args can only be vlc_tracer_entry and the va-args list should be ended by a vlc_tracer_entry with a NULL key.

Parameters

data	data pointer as provided to vlc_tracer_Trace().

Enumeration Type Documentation

vlc_tracer_value

enum vlc_tracer_value

Trace message values.

Enumerator
VLC_TRACER_INT
VLC_TRACER_TICK
VLC_TRACER_STRING

Function Documentation

vlc_tracer_TraceWithTs()

void vlc_tracer_TraceWithTs	(	struct vlc_tracer *	tracer,
		vlc_tick_t	ts,
			...
	)

Emit traces.

va-args are a list of key / value parameters. Key must be a not NULL string. Value has to be defined with one of the type defined in the vlc_tracer_entry union.

Parameters

tracer	tracer emitting the traces
ts	timestamp of the current trace
