VixDiskLib_Combine & VixDiskLib_Reparent Missing Api's

Hi,

I have downloaded the latest VDDK 5.1 and went through the docs where the docs has help for VixDiskLib_Combine and VixDiskLib_Reparent. But the include file vixDiskLib.h does not have any declaration for those functions. How do i use these function ?

vixError = VixDiskLib_Reparent(VixDiskLibConnection connection, const char *path, const char *parentHint);

 

vixError = VixDiskLib_Combine(VixDiskLibHandle diskHandle, uint32 linkOffsetFromBottom, uint32 numLinksToCombine, VixDiskLibProgressFunc progressFunc, void *progressCallbackData);

Any help on this.

/Thanks
