GetDriveType

3.0

The GetDriveType function determines whether a disk drive is removable, fixed, or remote.

Parameters

DriveNumber

Specifies the drive for which the type is to be determined (0 = drive A, 1 = drive B, 2 = drive C, and so on).

Return Value

The return value is DRIVE_REMOVABLE (disk can be removed from the drive), DRIVE_FIXED (disk cannot be removed from the drive), or DRIVE_REMOTE (drive is a remote, or network, drive), if the function is successful. Otherwise, the return value is zero.

Example

The following example uses the GetDriveType function to determine the drive type for all possible disk drives (letters A through Z):

int  iDrive;
WORD wReturn;
char szMsg[80];

for (iDrive = 0, wReturn = 0;
        (iDrive < 26) && (wReturn != 1); iDrive++) {

    wReturn = GetDriveType(iDrive);

    sprintf(szMsg, "drive %c: ", iDrive + 'A');

    





switch (wReturn) {
        case 0:
            strcat(szMsg, "undetermined");
            break;

        case DRIVE_REMOVABLE:
            strcat(szMsg, "removable");
            break;

        case DRIVE_FIXED:
            strcat(szMsg, "fixed");
            break;

        case DRIVE_REMOTE:
            strcat(szMsg, "remote (network)");
            break;
    }
    TextOut(hdc, 10, 15 * iDrive, szMsg, strlen(szMsg));
}
