Function Documentation

static void mb_progm_step	(	const mb_timeval_t *	tmo,
		const mb_timeval_t *	now,
		void *	arg
	)			[static]

Time stepping for a program.

Any two actions in concurrent words never change the same attribute. Start time of words in a program are specified in incremental order.

Note:

Program will take a big step at last monent. It is because mb_progm_step() running mb_word_stop() if the word being stop between now and next_tmo. It is not obviously if time stepping small.

Todo:

Leverage aspective programming to prevent problem of unittest.
