void destroy_eax_type

(

njb_eax_t *

eax

)

This function destroys an EAX type holder and free up the memory used by it.

Parameters:

eax

the EAX type holder to destroy

int eax_unpack	(	void *	data,
		size_t	nbytes,
		njb_state_t *	state
	)

This function inpacks an EAX block from the NJB1. The EAX effects are then added to the linked list in the device state and retrieved one by one by the user of the API.

Parameters:

	data	raw chunk of data to be converted to EAX effects
	nbytes	the size of the data chunk
	state	the device state that holds the linked list to add the effects to

Returns:

0 on success, -1 on failure

njb_eax_t* new_eax_type

(

void
