Compute Space Needed for Clone

This function computes the space required (in bytes) to clone a virtual disk, after possible format conversion.

vixError = VixDiskLib_SpaceNeededForClone(child.Handle(), VIXDISKLIB_DISK_VMFS_FLAT, &spaceReq);

Caution: VixDiskLib_SpaceNeededForClone() might not give accurate results, or could return VIX_E_INVALID_ARG, when used with thin provisioned disk type VIXDISKLIB_DISK_VMFS_THIN.
