◆ ioctl()

int PX4Magnetometer::ioctl	(	cdev::file_t *	filep,
		int	cmd,
		unsigned long	arg
	)

overridevirtual

Perform an ioctl operation on the device.

The default implementation handles DIOC_GETPRIV, and otherwise returns -ENOTTY. Subclasses should call the default implementation for any command they do not handle themselves.

Parameters
