Summary: The OpenFileMapping API

!!!!C# Signature:
 [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)]
 static extern IntPtr OpenFileMapping(
     uint dwDesiredAccess, 
     bool bInheritHandle,
     string lpName);
!!!!User-Defined Types:
None.

!!!!Notes:
None.

!!!!Tips & Tricks:
Please add some!

!!!!Sample Code:
		const UInt32 STANDARD_RIGHTS_REQUIRED = 0x000F0000;
		const UInt32 SECTION_QUERY = 0x0001;
		const UInt32 SECTION_MAP_WRITE = 0x0002;
		const UInt32 SECTION_MAP_READ = 0x0004;
		const UInt32 SECTION_MAP_EXECUTE = 0x0008;
		const UInt32 SECTION_EXTEND_SIZE = 0x0010;
		const UInt32 SECTION_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED|SECTION_QUERY|
			SECTION_MAP_WRITE |      
			SECTION_MAP_READ |       
			SECTION_MAP_EXECUTE |    
			SECTION_EXTEND_SIZE);
		const UInt32 FILE_MAP_ALL_ACCESS = SECTION_ALL_ACCESS;
		private IntPtr hHandle;
		private IntPtr pBuffer;
		unsafe public void Attach(string SharedMemoryName, UInt32 NumBytes)
		{
			if (IntPtr.Zero != hHandle) return;
			hHandle = OpenFileMapping(FILE_MAP_ALL_ACCESS, false, SharedMemoryName);
			if (IntPtr.Zero == hHandle) return;
			pBuffer = MapViewOfFile(hHandle, FILE_MAP_ALL_ACCESS, 0, 0, &NumBytes);
		}
		public void Detach()
		{
			if (IntPtr.Zero != hHandle)
			{ 
				CloseHandle(hHandle); //fair to leak if can't close
				hHandle = IntPtr.Zero;
			}
			pBuffer = IntPtr.Zero;
			lBufferSize = 0;
		}
