  19 /*  SYNOPSIS */
  20         AROS_LHA(struct PartitionHandle *, root,       A1),

  22 /*  LOCATION */
  23         struct Library *, PartitionBase, 19, Partition)

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