'\n' in QTcpSocket.write()

NintyS

Hello, I want to ask if there is a way to send string with '\n'? ( I don't want R"(string)", but if this is an only option then I will use it )

There are many ways to do it. You have read the QIODevice class docs, right? and you understand that const char* or QByteArray& can be passed to Write()?

After that it's just basic C/C++ programming.

But the more important question is what EXACTLY do you really want to send, <CR>? <LF>? <CR><LF>?

Streams based RFC protocols will specify exactly what they expect as an end-of-line sequence. Many text based protocols expect <CR><LF>.

@NintyS
There is no problem sending a newline (or any other character) via QTcpSocket.write(). If you do not want to write R"(string\n)" in your code you can always do it without the R literal string syntax via "string\\n". Or similarly as @Kent-Dorfman says if you need to send "string\\r\\n".
