使用vc ++中的WMI枚举分区驱动器盘符

我想获得计算机上的所有分区的系统盘符，除了活动分区，使用WMI，这是我到目前为止（我不知道如何得到驱动器号，以及如何检查他们都是硬盘驱动器或系统驱动器，所以我没有得到任何光盘在这里）：

std::vector<CString> GetPartitionsVector(bool bCoInit = false ) { std::vector<CString> partVect; HRESULT hres = NULL; if(bCoInit) { hres = CoInitializeEx(0, COINIT_MULTITHREADED); if (FAILED(hres)) { goto end_routine; } hres = CoInitializeSecurity( NULL, -1, // COM authentication NULL, // Authentication services NULL, // Reserved RPC_C_AUTHN_LEVEL_DEFAULT, // Default authentication RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation NULL, // Authentication info EOAC_NONE, // Additional capabilities NULL // Reserved ); if (FAILED(hres)) { goto end_routine; } } IWbemLocator *pLoc = NULL; hres = CoCreateInstance( CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID *) &pLoc); if (FAILED(hres)) { goto end_routine; } IWbemServices *pSvc = NULL; hres = pLoc->ConnectServer( _bstr_t(L"ROOT\\CIMV2"), // Object path of WMI namespace NULL, // User name.
