  20    AROS_LHA(struct PartitionHandle *, root,       A1),

  25 /*  FUNCTION
  26     Destroy a partition table by immediately overwriting table data on disk.
  27
  28     INPUTS
  29     root - partition table to destroy
  30
  31     RESULT
  32     0 on success; an error code otherwise
  33
  34     NOTES
  35     After calling this function the state of the PartitionHandle will be the
  36     same as before calling OpenPartitionTable(). Therefore do not reference
  37     any child PartitionHandles any more.
