Member Function Documentation

get_FileSysType()

FILESYS_TYPE Gray::cFileDevice::get_FileSysType ( ) const

inline

GetDeviceFreeSpace()

FILE_SIZE_t GRAYCALL Gray::cFileDevice::GetDeviceFreeSpace ( const FILECHAR_t *  pszDeviceId = nullptr )

static

Get disk space on the pszDeviceId.

Returns

the free disk space in bytes.

GetDeviceType()

UINT GRAYCALL Gray::cFileDevice::GetDeviceType ( const FILECHAR_t *  pszDeviceId )

static

Determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive. https://msdn.microsoft.com/en-us/library/windows/desktop/aa364939(v=vs.85).aspx

Returns

0 =DRIVE_UNKNOWN, 1=DRIVE_NO_ROOT_DIR, 2=DRIVE_REMOVABLE, 3=DRIVE_FIXED, 4=DRIVE_REMOTE, 5=DRIVE_CDROM, 6=DRIVE_RAMDISK

GetSystemDeviceList()

HRESULT GRAYCALL Gray::cFileDevice::GetSystemDeviceList ( cArrayString< FILECHAR_t > &  a )

static

list all the devices/volumes available to the system.

isCaseSensitive()

bool Gray::cFileDevice::isCaseSensitive

(

)

const

The file system is case sensitive ? linux = true, _WIN32 = false A network mounted SAMBA share will use whatever rules the native OS/FileSystem uses. m_sTypeName = "FAT","NTFS" system = non case sensitive. "NFS" = case sensitive.

UpdateInfo()

HRESULT Gray::cFileDevice::UpdateInfo

(

const FILECHAR_t *

pszDeviceId = nullptr

)

• pszDeviceId = nullptr = use the current dir/path for the app. pszDeviceId can be from _WIN32 GetLogicalDriveStrings() some drives won't be ready (if removable). Thats OK. HRESULT_WIN32_C(ERROR_NOT_READY)

Member Data Documentation

k_FileSysName

const char * Gray::cFileDevice::k_FileSysName

static

Initial value:

=
        {
                "",                     
                "FAT",          
                "FAT32",        
                "NTFS",         
                "NFS",          
        }

File system types i might support.
