Description of routines in cdrom.c

Only a few routines in cdrom.c are exported to the drivers. In this section we will treat these, as well as the functioning of the routines that `take over' the interface to the kernel. The header file belonging to cdrom.c is called ucdrom.h, but may be included in cdrom.h in the future.

• struct file_operations cdrom_fops
• Int register_cdrom(int major, char*name, structI>cdrom_device_ops *cdo)
• Int unregister_cdrom(int major, char*name)
• Int cdrom_open(struct inode*ip, struct file*fp)
• Void cdrom_release(struct inode*ip, struct file*fp)
• Int cdrom_ioctl (struct inode*ip, struct file*fp, unsigned int cmd, unsigned long arg)
  • Directly implemented ioctls
  • Ioctls rooted through audio_ioctl ()
  • New ioctls in cdrom.c
  • Device dependent iocts
