[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns the details of all partitions on the current disk.

Syntax

HRESULT QueryPartitions(
  [out] VDS_PARTITION_PROP **ppPartitionPropArray,
  [out] LONG               *plNumberOfPartitions
);

Parameters

[out] ppPartitionPropArray

A pointer to the array of VDS_PARTITION_PROP structures passed in by the caller. Callers must free this array by using the CoTaskMemFree function.

[out] plNumberOfPartitions

A pointer to the number of elements in the array returned in the ppPartitionPropArray parameter.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code	Description
S_OK	The query was successful.
S_FALSE	The disk contains no partitions.

Remarks

If the disk contains extended partitions, this method returns only the first extended partition, regardless of how many extended partitions are on the disk. A disk contains one extended partition for each logical drive. For more information about logical drives, see Disk Object.
