SHQueryRecycleBinW function (shellapi.h)
Retrieves the size of the Recycle Bin and the number of items in it, for a specified drive.
SHSTDAPI SHQueryRecycleBinW( [in, optional] LPCWSTR pszRootPath, [in, out] LPSHQUERYRBINFO pSHQueryRBInfo );
[in, optional] pszRootPath
The address of a null-terminated string of maximum length MAX_PATH to contain the path of the root drive on which the Recycle Bin is located. This parameter can contain the address of a string formatted with the drive, folder, and subfolder names (C:\Windows\System...).
[in, out] pSHQueryRBInfo
The address of a SHQUERYRBINFO structure that receives the Recycle Bin information. The cbSize member of the structure must be set to the size of the structure before calling this API.
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
With Windows 2000, if NULL is passed in the pszRootPath parameter, the function fails and returns an E_INVALIDARG error code. In earlier versions of the operating system, you can pass an empty string or NULL. If pszRootPath contains an empty string or NULL, information is retrieved for all Recycle Bins on all drives.
The shellapi.h header defines SHQueryRecycleBin as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
