IShellFolder::GetDisplayNameOf return 乱码

Question

我是 winapi 和 c/c++ 的新手，我尝试使用 IShellFolder::GetDisplayNameOf 打印出桌面上图标的名称，但由于某种原因，我遇到了乱码。这是我的代码：

    int main() {
    HRESULT hr;
    IShellFolder* deskFolder;
    hr = SHGetDesktopFolder(&deskFolder);
    IEnumIDList* listilist;
    deskFolder->EnumObjects(NULL, SHCONTF_NONFOLDERS | SHCONTF_FOLDERS, &listilist);
    ITEMIDLIST* item;
    deskFolder->Release();
    while (listilist->Next(1, &item, NULL) == S_OK) {
        STRRET coo = {0};
        deskFolder->GetDisplayNameOf(item, SHGDN_INFOLDER, &coo);
        printf("%s\n", coo.cStr);
        item = NULL;
    }
    return 0;
}

根据 document:

uType

Type: UINT

A value that specifies the desired format of the string. This can be one of the following values.

STRRET_CSTR

The string is returned in the cStr member.

STRRET_OFFSET

The uOffset member value indicates the number of bytes from the beginning of the item identifier list where the string is located.

STRRET_WSTR

The string is at the address specified by pOleStr member.

可以查看coo的utype参数：

printf("%d\n", coo.uType);

经查其return值为0（STRRET_WSTR），所以需要修改代码为

printf("%S\n", coo.pOleStr);
