for legacy and new drivers. This is an opcode for ioctl that can be used on almost any device entry found in /dev. When used, ioctl will fill a buffer with the absolute path to the driver file that is being used by the device. This opcode was available in BeOS R5, though remained unimplemented in Haiku since the introduction of the Device Manager almost two decades ago. Original change by Jacob Secunda.
