TWUCleanupDownloads

The TWUCleanupDownloads function deletes all downloaded files of the session. You can use this function to clean up the temporary package installer files that were used during the session.

Tip: To prevent deletion of one or more download files, set the szDownloadPath member of their TWUPackageData to an empty string (use pPackage->szDownloadPath[0] = 0; or pPackage^.szDownloadPath[0] := #0; in Delphi)

): URESULT;

Parameters

Return value

If the function succeeds, it returns ERROR_SUCCESS (0). If it fails, it returns a nonzero Win32 API error code. You can use TWUGetErrorMessage to retrieve the error message that corresponds to the error code.
