[OCLUG-Tech] 'C' used in drivers question?

[William Case <billlinux [ at ] rogers [ dot ] com>]

Hi;

I am patiently reading the O'Reily "Linux Device Drivers" and have come
across the following line (and several like it):

int (*open) (struct inode *, struct file *)

I can interpret most of the line except the 'inode *' and 'file *'.  I
have never seen the asterisk in C used in this fashion.  What does it
mean?
