Overview
The GetVolumeType function retrieves the type of physical or logical device mapped to the drive letter.
Syntax/Parameters
Syntax
int = GetVolumeType ( string volume );
Parameters
volume
A string containing the drive letter. Any characters after the first letter are ignored.
Return Value
Returns an int specifying the type of device or -1 on failure. Use the GetLastError function to retrieve error information. The lower word portion of the error code will contain the Windows SDK drive type code (normally 0 or 1 for unknown device or for no root directory on device).
The return codes are as follows (as defined in the Legato and Windows SDK):
| Define | Value | Comment | |||
| DRIVE_UNKNOWN | 0 | Function returns as error | |||
| DRIVE_NO_ROOT_DIR | 1 | Function returns as error | |||
| DRIVE_REMOVABLE | 2 | SD, Thumb Drive, etc... | |||
| DRIVE_FIXED | 3 | Local, (typically C drive) | |||
| DRIVE_REMOTE | 4 | Network share | |||
| DRIVE_CDROM | 5 | CD or DVD drive | |||
| DRIVE_RAMDISK | 6 | RAM (memory based) disk |
Remarks
The GetVolumeType function does not test whether the volume actually exists, only that it is mapped. For example, the function will return without error for a CD or DVD drive when the drive is empty. Any data in the volume parameter after the drive letter is ignored.
