ushort* to IntPtr conversion

[C# Programming]

How do I convert a ushort* to an IntPtr?

Or any primitive pointer to an IntPtr? int*, uint*, etc..

Background:

The ushort* holds the start address to a buffer from a PInvoke call:
[DllImport( "DCamLIB.dll" )]
private unsafe static extern bool DcamCapture( ushort* imageBuffer, Int32 bufferSize );


I need to then pass this ******** on complete with buffer size to a C# method that takes a IntPtr.

Thanks in advance,

Jason
