IVdsVolumeMF::AddAccessPath method (vds.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Adds an access path.
Syntax
HRESULT AddAccessPath(
[in] LPWSTR pwszPath
);
Parameters
[in] pwszPath
A string indicating the access path, which is a user-mode path that can be used to open the volume. An access path can be a drive letter or a path to an empty directory on an NTFS volume. The access path string must include a trailing backslash, for example, "F:".
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/value | Description |
|---|---|
|
The path was added successfully. |
|
The access path was added successfully, however, an error occurred. VDS possibly failed to update the GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER attribute of a partition or failed to add a default network share (such as F$) while adding the drive letter. For more information, see PARTITION_INFORMATION_GPT. |
|
The volume failed. |
|
The pack containing the volume is not accessible. |
Remarks
VDS adds the access path by creating a mounted folder (also called a volume mount point). Note that mounted folders are supported only on NTFS volumes. For more information, see Mounted Folders.
This method returns ERROR_DIR_NOT_EMPTY if the pwszPath parameter contains a path to a mounted folder that is already in use (even if the directory is empty) or if pwszPath contains a path to a nonempty directory.
