Can I dump out the fuse contents from Atmega328?

I would like to dump out the fuse contents from Arduino Atmega328. May I know if this is possible?

With avrdude, a programmer and the ICSP header or from within a sketch ?

Both are possible.

boot_lock_fuse_bits_get(GET_LOW_FUSE_BITS);
boot_lock_fuse_bits_get(GET_HIGH_FUSE_BITS);
boot_lock_fuse_bits_get(GET_EXTENDED_FUSE_BITS);
