Summary: The SetFilePointerEx API

!!!!C# Signature:
 [DllImport("kernel32.dll")]
 static extern bool SetFilePointerEx(IntPtr hFile, long liDistanceToMove,
   IntPtr lpNewFilePointer, uint dwMoveMethod);

!!!!C# Signature:
 [DllImport("kernel32.dll")]
 public static extern bool SetFilePointerEx(
     SafeFileHandle hFile, long liDistanceToMove,
     out long lpNewFilePointer, uint dwMoveMethod);

!!!!User-Defined Types:
None.

!!!!Notes:
None.

!!!!Tips & Tricks:
The third argument (lpNewFilePointer) is of type LARGE_INTEGER, which has a size of 64 bytes. For this reason use a UInt64 for this argument. (See sample below)

!!!!Sample Code:
UInt64 n = 0; //it is important to use UInt64, because the 3rd argument is of type PLARGE_INTEGER, where LARGE_INTEGER has a size of 64 bytes.
IntPtr ptr = new IntPtr(&n);
SetFilePointerEx(handle, 0, ptr, FILE_CURRENT);//ptr contains current location of file pointer. handle is a pointer to an open file handle.

!!!!Alternative Managed API:
Do you know one?  Please contribute it!
