socket 编程 recv 调用能否每次最多读一行?

[mantianyu]

When communicating with serial port, I can set the serial port in Canonical Mode so that each read() call will return util a line comes, and at most one line.

assumes the line separator is \r\n.

Does TCP/IP communication support this feature?

I know that TCP/IP is based on stream and will take 'a','b','c' and '\r','\n' all the same, but I really don't want to parse the message char by char to find '\r','\n' in application.

I hope the TCP can do it for me...

any idea?

do it yourself

This is definitely application logic, which TCP should not handle.

So keep calm and implement it yourself.

socket.makefile
then readline

while ‘\r\n’ not in data
data+=recv()

噗，肯定要缓存结果的，TCP是8位流又不是数据包。
