Detailed Description

Module for gathering statistics about transactions.

This module maintains both aggregate statistics about all threads (aggregates are updated upon thread cleanup) and per-thread statistics. The built-in statistics of the core STM library are more efficient and detailed but this module is useful in case the library is compiled without support for statistics.

Function Documentation

void mod_stats_init

(

void

)

Initialize the module.

This function must be called once, from the main thread, after initializing the STM library and before performing any transactional operation.

int stm_get_global_stats	(	const char *	name,
		void *	val
	)

Get various statistics about the transactions of all threads.

See the source code (mod_stats.c) for a list of supported statistics.

Parameters

name	Name of the statistics.
val	Pointer to the variable that should hold the value of the statistics.

Returns

1 upon success, 0 otherwise.

int stm_get_local_stats	(	const char *	name,
		void *	val
	)

Get various statistics about the transactions of the current thread.

See the source code (mod_stats.c) for a list of supported statistics.

Parameters

name	Name of the statistics.
val	Pointer to the variable that should hold the value of the statistics.
