I wonder what the basic options for QTCPSocket are.

[keyboard_hellchang]

Hi.
my qt version 4.8.7
my OS is centos7

I wonder what the default options for QTCPSocket are.
LowDelayOption??
KeepAlive??

Do I need to set up in a .pro file or Makefile, not a code?

Please Help me!!!

Have you tried to search in documentation?

• QAbstractSocket::LowDelayOption

Try to optimize the socket for low latency. For a QTcpSocket this would set the TCP_NODELAY option and disable Nagle's algorithm. Set this to 1 to enable.

• QAbstractSocket::KeepAliveOption

Set this to 1 to enable the SO_KEEPALIVE socket option

@keyboard_hellchang Qt is open source, so you can simply check the QTCPSocket implementation (default constructor) to see how socket is initialized.
