When accessing a device file, the major number selects which device driver is being called to perform the input/output operation. This call is being done with the minor number as a parameter and it is entirely up to the driver how the minor number is being interpreted. The driver documentation usually describes how the driver uses minor numbers. .:: podcasts.apple.com ::. .:: postheaven.net ::. .:: caramel.la ::. .:: podcasts.apple.com ::.
