devfs_mk_cdev question

["Paul Akkermans" <paulakkermans@wanadoo.nl>]

Hi group,

 

Can anybody tell me what happens in this piece of code:

 

mousedev_table[minor] = mousedev;

 

 devfs_mk_cdev(MKDEV(INPUT_MAJOR, MOUSEDEV_MINOR_BASE + minor),
   S_IFCHR|S_IRUGO|S_IWUSR, "input/mouse%d", minor);
 class_simple_device_add(input_class,
    MKDEV(INPUT_MAJOR, MOUSEDEV_MINOR_BASE + minor),
    dev->dev, "mouse%d", minor);

 

I am especially interested in devfs_mk_cdev and what is means.

 

Can anybody help me?

 

Thanks in advance,

 

PA
