Get names of all current drives / media (discs, USB devices) connected to the computer.

I wrote a nice function that detects all currently connected drives.

The function will then find out the names (letters) of the connected units.

The outup of the function is datetype ::std::vektor<::std::string>, which returns the stored units in the vector data type.

Function design:

::vector<::std::string>GetDriverLabel(void)
 {
    ::std::vector <::std::string> volumelabels;
    ::HANDLE hDevice;
    char drv;
    const char *charDrv;
    drv='A';
  
    while(drv!='[')
    {
       ::std::stringstream Str;
       ::std::string drvStr;
       Str<<drv;
       Str>>drvStr;
       ::std::string drvSpc=drvStr+":";
       ::std::string fCheck="\\\\.\\";
       ::std::string fhCheck=fCheck+drvStr+":";
       charDrv=drvSpc.c_str();
       ::std::wstring stemp = ::std::wstring(fhCheck.begin(),  fhCheck.end());
       ::LPCWSTR sw = stemp.c_str();
       hDevice=::CreateFile(sw, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, 
                            NULL, OPEN_EXISTING, 0, NULL);
 
      if(hDevice!=INVALID_HANDLE_VALUE)
      {
         ::std::wstring stemp = ::std::wstring(drvSpc.begin(),  drvSpc.end());
         ::LPCWSTR sw = stemp.c_str();

         switch(GetDriveType(sw))
         {
            case DRIVE_FIXED:
            {
               volumelabels.push_back(charDrv);
               break;
            }
            case DRIVE_REMOVABLE:
            {
               volumelabels.push_back(charDrv);
               break;
            }
            case DRIVE_NO_ROOT_DIR:
            {
               volumelabels.push_back(charDrv);
               break;
            }
            case DRIVE_REMOTE:
            {
               volumelabels.push_back(charDrv);
               break;
            }
            case DRIVE_CDROM:
            {
               break;
            }
            case DRIVE_RAMDISK:
            {
               break;
            }
            case DRIVE_UNKNOWN:
            {
               break;
            }
         }
     }
      drv++;
    }
    return volumelabels;
 }

-----------------------------------------------------------------

The whole function is built into header WinAPI.h ►WinAPI.h◄

#include "WinAPI.h" //https://www.netbot.sk/en/14-blog-headers/44-winapi-en

int _cdecl main (void) 
{
    ::Diall_WinApi::WinApi::GetInstance()->SystemIntegrity(::Diall_WinApi::Privilege::ENABLE); 

    ::std::vector<::std::string> label = ::Diall_WinApi::WinApi::GetInstance()->GetDriverLabel();

    //Zobrazenie pripojenych jednotiek odpredu.//
    for (std::vector<::std::string>::iterator it = label.begin() ; it != label.end(); ++it)
    {
        ::std::cout << *it << "\n";
    }

    //Zobrazenie pripojenych jednotiek odzadu. Nutne pouzit Release Mod!//
    for (vector::iterator it = label.end()-1; it != label.begin()-1; it--)
   {
      ::std::cout << *it << "\n";
   }

   return 0;
}
