◆ xpt_path_sim_device()

device_t xpt_path_sim_device ( const struct cam_path * path )

Return the device_t associated with the path.

When a SIM is created, it registers a bus with a NEWBUS device_t. This is stored in the internal cam_eb bus structure. There is no guarnatee any given path will have a device_t associated with it (it's legal to call xpt_bus_register with a NULL device_t.
