C++ Windows에서 하드드라이브 정보 읽어오기 : GetVolumeInformation

MSDN에 보면 GetVolumeInformation라는 함수를 찾아 볼수 있다.

함수는 아래와 같이 생겼다.

C++

BOOL WINAPI GetVolumeInformation(
  _In_opt_   LPCTSTR lpRootPathName,
  _Out_opt_  LPTSTR lpVolumeNameBuffer,
  _In_       DWORD nVolumeNameSize,
  _Out_opt_  LPDWORD lpVolumeSerialNumber,
  _Out_opt_  LPDWORD lpMaximumComponentLength,
  _Out_opt_  LPDWORD lpFileSystemFlags,
  _Out_opt_  LPTSTR lpFileSystemNameBuffer,
  _In_       DWORD nFileSystemNameSize
);

자세한 설명은 아래 MSDN 페이지를 참고하면 된다.

사용 예제는 아래를 참고하면 된다.

#include <atlstr.h> #include <iostream> using std::wcout; using std::endl; int _tmain(int argc, _TCHAR* argv[]) {         _TCHAR buffer[256] = { 0, };         CString DrivePathName;         int n = 0;         _TCHAR DriveName[100];         _TCHAR FileSystem[100];         LPCTSTR    drivename;         GetLogicalDriveStrings(256, buffer);         DWORD lVolumnSerialNumber;         while (buffer[n] != NULL)         {                for (int i = 0; i < sizeof(*(buffer + n)); i++)                {                        DrivePathName = buffer + n;                        n += 4;                        ZeroMemory(DriveName, sizeof(DriveName));                        ZeroMemory(FileSystem, sizeof(FileSystem));                        ZeroMemory(&drivename, sizeof(drivename));                        GetVolumeInformation(DrivePathName, DriveName, 1024,                            &lVolumnSerialNumber, NULL, NULL, FileSystem, 1024);                        wcout << "Path                 : " << DrivePathName.GetBuffer() << endl;                        wcout << "DriverName           : " << DriveName << endl;                        wcout << "FileSystem           : " << FileSystem << endl;                        wcout << "Volumn Serial Number : ";                        printf("%X\n\n", lVolumnSerialNumber);                }         }         return 0; }

참고로 Unicode로 Project를 만들어서 wcout 를 사용하였다.
