These instances are registered with the kernel by the -.Ft device_create() -function. - -The major number identifies the driver and the minor number identifies -the device itself. The major number must be allocated with the -.Ft device_alloc_major() -function. - -If the device blocksize is greater than 1, this device is considered a block -device, otherwise if it is 1, it is considered a character device. - -.Sh AUTHORS -.An Ian Moffett Aq Mt ian@osmora.org |
