typedef void (*PMICCallback)(PMIC_ERR result, void* arg);

PMIC_ERR PMICCloseAsync(PMICCallback cb, void* arg);

Return Values

Returns one of the following.

PMIC_ERR_OK	The function has been called normally.

PMIC_ERR_OK	The Wii Speak has been closed successfully.
PMIC_ERR_NO_DEVICE	The Wii Speak has been unplugged.
PMIC_ERR_USB_ERROR	An error occurred in USB communications. Call the function again.
PMIC_ERR_FATAL	A fatal error has occurred.
