Receive a Line Terminated by CRLF
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveToCRLF, which receives text through a CRLF line terminator and returns the text including the terminator.
Background. Chilkat encodes CR followed by LF using
StringCharset and searches the incoming byte stream for that exact sequence. This is convenient for line-oriented text protocols.Chilkat Objective-C Downloads
