Remarks
Reads a chunk of data from the socket and gathers the source address.
A return value of 'true' does not necessarily mean that data was returned. Callers must check the 'BytesRead' parameter for the actual amount of data returned. A value of zero indicates that there was no data available for reading. true on success, false in case of a closed socket or an unrecoverable error.
