System.Net.Sockets.SocketAsyncEventArgs.InnerStartOperationReceive C# (CSharp) Method

        private void InnerStartOperationReceive()

            // WWSARecv uses a WSABuffer array describing buffers of data to send.
            //

            // performance for the more common single buffer case.  
            //
            // For a single buffer:
            //   The Overlapped.UnsafePack method is used that takes a single object to pin.
            //   A single WSABuffer that pre-exists in SocketAsyncEventArgs is used.
            //
            // For multiple buffers:
            //   The Overlapped.UnsafePack method is used that takes an array of objects to pin.
            //   An array to reference the multiple buffer is allocated.
            //   An array of WSABuffer descriptors is allocated.
