示例1: BeginReceive
/*++
Routine Description:
BeginReceive - Async implimentation of Recv call,
Called when we want to start an async receive.
We kick off the receive, and if it completes synchronously we'll
call the callback. Otherwise we'll return an IASyncResult, which
the caller can use to wait on or retrieve the final status, as needed.
Uses Winsock 2 overlapped I/O.
Arguments:
ReadBuffer - status line that we wish to parse
Index - Offset into ReadBuffer to begin reading from
Size - Size of Buffer to recv
Callback - Delegate function that holds callback, called on completeion of I/O
State - State used to track callback, set by caller, not required
Return Value:
IAsyncResult - Async result used to retreive result
