Shell question - writing PIDL's to file?

[fabio]

This is an example of how we can create a shortcut file:

// CreateLink - uses the Shell's IShellLink and IPersistFile interfaces 
//              to create and store a shortcut to the specified object. 
//
// Returns the result of calling the member functions of the interfaces. 
//
// Parameters:
// lpszPathObj  - address of a buffer containing the path of the object. 
// lpszPathLink - address of a buffer containing the path where the 
//                Shell link is to be stored. 
// lpszDesc     - address of a buffer containing the description of the 
//                Shell link. 

HRESULT CreateLink(LPCSTR lpszPathObj, LPCSTR lpszPathLink, LPCSTR lpszDesc) 
{ 
    HRESULT hres; 
    IShellLink* psl; 
 
    // Get a pointer to the IShellLink interface. 
    hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, 
                            IID_IShellLink, (LPVOID*)&psl); 
    if (SUCCEEDED(hres)) 
    { 
        IPersistFile* ppf; 
 
        // Set the path to the shortcut target and add the description. 
        psl->SetPath(lpszPathObj); 
        psl->SetDescription(lpszDesc); 
 
        // Query IShellLink for the IPersistFile interface for saving the 
        // shortcut in persistent storage. 
        hres = psl->QueryInterface(IID_IPersistFile, (LPVOID*)&ppf); 
 
        if (SUCCEEDED(hres)) 
        { 
            WCHAR wsz[MAX_PATH]; 
 
            // Ensure that the string is Unicode. 
            MultiByteToWideChar(CP_ACP, 0, lpszPathLink, -1, wsz, MAX_PATH); 
			
            // Add code here to check return value from MultiByteWideChar 
            // for success.
 
            // Save the link by calling IPersistFile::Save. 
            hres = ppf->Save(wsz, TRUE); 
            ppf->Release(); 
        } 
        psl->Release(); 
    } 
    return hres; 
}

This example can be modified to save an ITEMIDLIST to a file by replacing:

psl->SetPath(lpszPathObj); 

with:

psl->SetIDList(some_pidl)

Now, is there a way to save several ITEMIDLIST's to a single file?
Thank you in advance.

Is it a file that complies with some predefeined format or just one you can make up yourself?
