FindNextVolumeW function (fileapi.h)

Continues a volume search started by a call to the FindFirstVolume function. FindNextVolume finds one volume per call.


BOOL FindNextVolumeW(
  [in]  HANDLE hFindVolume,
  [out] LPWSTR lpszVolumeName,
  [in]  DWORD  cchBufferLength


[in] hFindVolume

The volume search handle returned by a previous call to the FindFirstVolume function.

[out] lpszVolumeName

A pointer to a string that receives the volume GUID path that is found.

[in] cchBufferLength

The length of the buffer that receives the volume GUID path, in TCHARs.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError. If no matching files can be found, the GetLastError function returns the ERROR_NO_MORE_FILES error code. In that case, close the search with the FindVolumeClose function.


After the search handle is established by calling FindFirstVolume, you can use the FindNextVolume function to search for other volumes.

You should not assume any correlation between the order of the volumes that are returned by these functions and the order of the volumes that are on the computer. In particular, do not assume any correlation between volume order and drive letters as assigned by the BIOS (if any) or the Disk Administrator.
