bool mon_clear_timed	(	struct monster *	m_ptr,
		int	ef_idx,
		u16b	flag,
		bool	id
	)

Clears the timed effect ef_idx.

Returns TRUE if the monster's timer was changed.

bool mon_dec_timed	(	struct monster *	m_ptr,
		int	ef_idx,
		int	timer,
		u16b	flag,
		bool	id
	)

Decreases the timed effect ef_idx by timer.

Calculates the new timer, then passes that to mon_set_timed(). If a timer would be set to a negative number, it is set to 0 instead. Note that decreasing a timed effect should never fail.

Returns TRUE if the monster's timer changed.

bool mon_inc_timed	(	struct monster *	m_ptr,
		int	ef_idx,
		int	timer,
		u16b	flag,
		bool	id
	)

Increases the timed effect ef_idx by timer.

Calculates the new timer, then passes that to mon_set_timed(). Note that each effect has a maximum number of turns it can be active for. If this function would put an effect timer over that cap, it sets it for that cap instead.

Returns TRUE if the monster's timer changed.

		u16b	flag
	)

static

Determines whether the given monster successfully resists the given effect.

If MON_TMD_FLG_NOFAIL is set in flag, this returns FALSE. Then we determine if the monster resists the effect for some racial reason. For example, the monster might have the NO_SLEEP flag, in which case it always resists sleep. Or if it breathes chaos, it always resists confusion. If the given monster doesn't resist for any of these reasons, then it makes a saving throw. If MON_TMD_MON_SOURCE is set in flag, indicating that another monster caused this effect, then the chance of success on the saving throw just depends on the monster's native depth. Otherwise, the chance of success decreases as timer increases.

Also marks the lore for any appropriate resists.

		bool	id
	)

static

Attempts to set the timer of the given monster effect to timer.

Checks to see if the monster resists the effect, using mon_resist_effect(). If not, the effect is set to timer turns. If timer is 0, or if the effect timer was 0, or if MON_TMD_FLG_NOTIFY is set in flag, then a message is printed, unless MON_TMD_FLG_NOMESSAGE is set in flag.

Set a timed monster event to 'v'. Give messages if the right flags are set. Check if the monster is able to resist the spell. Mark the lore. Returns TRUE if the monster was affected. Return FALSE if the monster was unaffected.
