IVssFileShareSnapshotProvider::GetSnapshotProperties method (vsprov.h)

Gets the VSS_SNAPSHOT_PROP structure for a file share snapshot.


HRESULT GetSnapshotProperties(
  [in]  VSS_ID            SnapshotId,
  [out] VSS_SNAPSHOT_PROP *pProp


[in] SnapshotId

Shadow copy identifier.

[out] pProp

The address of a caller-allocated VSS_SNAPSHOT_PROP structure that receives the shadow copy properties. The provider is responsible for setting the members of this structure. All members are required except m_pwszExposedName and m_pwszExposedPath, which the provider can set to NULL. The provider allocates memory for all string members that it sets in the structure. When the structure is no longer needed, the caller is responsible for freeing these strings by calling the VssFreeSnapshotProperties function.
