Ah, I think that is mentioned in some part of the documentation, but
the 'c' partition is special and actually refers to the whole slice.   
Generally it should say 'unused' in the fstype column for partition c.
Then you just use it as a reference number and do not consider it
in the partitions you create.

Here is a disk on a machine I am logged in to right now for example.


8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  2514944        0    4.2BSD     2048 16384    89   # (Cyl.    0 - 156*)
  b:  4618240  2514944      swap                        # (Cyl.  156*- 444*)
  c: 35551782        0    unused        0     0         # (Cyl.    0 - 2212*)
  e:  2514944  7133184    4.2BSD     2048 16384    89   # (Cyl.  444*- 600*)
  f: 25903654  9648128    4.2BSD     2048 16384    89   # (Cyl.  600*- 2212*)

Note that the a,b,e and f partitions add up to the c partition
and that the fstype for c is unused.
