Below is a certain function in c++.....
OTMSTATUS OTMAPI Otm_CreateSnapShotW(
IN    pOpenTransactionInW  In,
IN    ULONG NumVolumes,
IN    PVOID InVolumeMap,
IN    ULONG *VolumeMapFlags,
IN    ULONG OutVolumeMapByteSize,
INOUT PVOID OutVolumeMap,
OUT   pOpenTransactionOutW Out,
OUT   pSnapShot *SnapShot
INOUT LPOVERLAPPED Overlapped,
IN    LPOVERLAPPED_COMPLETION_ROUTINE CompletionRoutine
                               );

How would i PInvoke it so taht I can use it in C#?
INOUT PVOID OutVolumeMap is the output given by the function and it is in
the form of a string array.How would I define OutVolumeMap so that it would
give me the right result??

Thanks and Regards
