Receive Bytes up to a Delimiter into a BinData
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveUntilByteBd, which reads bytes until a delimiter byte is encountered and appends all bytes up to and including the delimiter to a BinData.
Background. The delimiter is a raw byte value from 0 through 255. This is useful for framing schemes that terminate each message with a known delimiter byte.
