HT_TP_DYN_STRACEPOINT

#define HT_TP_DYN_STRACEPOINT	(		timeline,
			label
	)		HT_TP_SCOPED_INT(timeline, (uintptr_t)ht_feature_cached_string_add_mapping_dynamic(timeline, label));

Creates a tracepoint that measures time spent in the scope.

This method is slower than HT_TP_STRACEPOINT(), but allows user to use dynamic strings for label.

Parameters

timeline	a timeline where the event will be posted to.
label	a string label of the tracepoint.

HT_TP_FUNCTION

#define HT_TP_FUNCTION

(

timeline

)

HT_TP_STRACEPOINT(timeline, __func__)

Generates a tracepoint that measures time spent in the function.

The macro shoudl be called as a first instruction of the traced function.

Parameters

timeline

a timeline where the event will be posted to.

HT_TP_STRACEPOINT

#define HT_TP_STRACEPOINT	(		timeline,
			label
	)

Value:

static HT_THREAD_LOCAL uintptr_t HT_UNIQUE_VAR_NAME(fnc_track) = ht_feature_cached_string_add_mapping(timeline, label); \
    HT_TP_SCOPED_INT(timeline, (uintptr_t)HT_UNIQUE_VAR_NAME(fnc_track));

Creates a tracepoint that measures time spent in the scope.

The label must be a static string. If it's not, use HT_TP_DYN_STRACEPOINT() instead.

Parameters

timeline	a timeline where the event will be posted to.
label	a string label of the tracepoint.
