TcpSettings

Settings that affect a connected socket.

Used as a member in struct TcpMsgSessionSettings.

struct TcpSettings
{
    TcpSettings() :
        sendBufSize(-1),
        recBufSize(-1),
        enableNagle(false),
        enableKeepAlive(false),

    int keepaliveinterval;
};

ssize_t sendBufSize

SO_SNDBUF setting. -1 means use the system default.

Default value : -1

---

ssize_t recBufSize

SO_RCVBUF setting. -1 means use the system default.

Default value : -1

---

bool enableNagle

If false then TCP_NODELAY option is set

---

bool enableKeepAlive

If true then SO_KEEPALIVE option is set

Time for next keep alive in millisec

Default value : 7200000 (2 hours)

---

int keepaliveinterval

Retranmission timeout in milliseconds if ACK not received Typically after 5 failures an error will be reported.
