AddPartition()

Synopsis

struct PartitionHandle * AddPartition(
         struct PartitionHandle * root,
         const struct TagItem * taglist );

struct PartitionHandle * AddPartitionTags(
         struct PartitionHandle * root,
         TAG tag, ... );

Function

Add a new partition.

Inputs

root - PartitionHandle, where to add the new partition
taglist - tags that specify more information about the partition
          unknown tags are ignored
    PT_DOSENVEC - ptr to a DosEnvec
        de_LowCyl and de_HighCyl specify start and end of cylinder
        de_Reserved, de_Bootblocks, ...
        de_Surfaces, de_BlocksPerTrack, ... are inherited from "root"
    PT_TYPE     - partition type (depends on PartitionTable type)
    PT_POSITION - position number within the partition table (MBR->PC)
    PT_ACTIVE   - set this partition active (MBR->PC)
    PT_NAME     - set partition name (HD0, HD1, ...)

Result

PartitionHandle of the new partition; 0 for an error

CreatePartitionTable()

Synopsis

LONG CreatePartitionTable(
         struct PartitionHandle * root,
         ULONG type );

Function

Create a new partition table.

Inputs

root - partition to create table in
type - the type of the partition table to create

Result

0 on success; an error code otherwise

Notes

After calling this function the state of the PartitionHandle will be
the same as when calling OpenPartitionTable(). Therefore before
closing the PartitionHandle you should call ClosePartitionTable().

DeletePartition()

Synopsis

void DeletePartition(
         struct PartitionHandle * ph );

Function

Delete a partition along with its subpartitions.

Inputs

ph - PartitionHandle to delete

DestroyPartitionTable()

Synopsis

LONG DestroyPartitionTable(
         struct PartitionHandle * root );

Function

Destroy a partition table by immediately overwriting table data on
disk.

Inputs

root - partition table to destroy

Result

0 on success; an error code otherwise

Notes

After calling this function the state of the PartitionHandle will be
the same as before calling OpenPartitionTable(). Therefore do not
reference any child PartitionHandles any more.

SetPartitionAttrs()

Synopsis

LONG SetPartitionAttrs(
         struct PartitionHandle * ph,
         const struct TagItem * taglist );

LONG SetPartitionAttrsTags(
         struct PartitionHandle * ph,
         TAG tag, ... );

Function

Set attributes of a partition

Inputs

ph      - PartitionHandle
taglist - list of attributes; unknown tags are ignored

SetPartitionTableAttrs()

Synopsis

LONG SetPartitionTableAttrs(
         struct PartitionHandle * root,
         const struct TagItem * taglist );

LONG SetPartitionTableAttrsTags(
         struct PartitionHandle * root,
         TAG tag, ... );

Function

Set attributes of a partition table.

Inputs

ph      - PartitionHandle of the partition table
taglist - list of attributes; unknown tags are ignored

WritePartitionDataQ()

Synopsis

LONG WritePartitionDataQ(
         struct PartitionHandle * Partition,
         APTR Buffer,
         ULONG DataSize,
         UQUAD StartBlock );

Function

Write raw data to the partition.

Inputs

Partition  - a handle to a partition to read from
Buffer     - a pointer to a data buffer
DataSize   - Size of data to read in bytes. This size must be a
             multiple of block size in order to ensure correct
             operation.
StartBlock - Number of the first block to start writing from.

Result

Return code of DoIO() function which was used to write the data.

WritePartitionTable()

Synopsis

LONG WritePartitionTable(
         struct PartitionHandle * root );

Function

Write a partition table; writing this partition table doesn't affect
subpartition tables.

Inputs

root - partition table to write

Result

0 for success; an error code otherwise
