IVdsService::QueryFileSystemTypes method (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns property details for all file systems known to VDS.

Syntax

HRESULT QueryFileSystemTypes(
  [out] VDS_FILE_SYSTEM_TYPE_PROP **ppFileSystemTypeProps,
  [out] LONG                      *plNumberOfFileSystems
);

Parameters

[out] ppFileSystemTypeProps

The address of a pointer to a buffer holding an array of VDS_FILE_SYSTEM_TYPE_PROP structures. Callers must free the memory for the array and for the pwszIllegalLabelCharSet string by using the CoTaskMemFree function.

[out] plNumberOfFileSystems

The total number of file systems.

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.
