示例1: connect
void TcpClient::connect(const IpAddress& address, NetPort port, const Duration& timeout, const Duration& pause)
{
Expect(address.isValid(), Throw(InvalidParameter, "Invalid IpAddress"));
Expect(port != NetPort_Any, Throw(InvalidParameter, "Invalid NetPort"));
int ret;
Clock clock;
Socket::create(address.getProtocol());
prv::SockAddrBuffer buffer(address, port);
clock.start();
do
{
ret = ::connect(getHandler(), buffer.getSockAddr(), buffer.getLength());
if(ret != 0)
{
std::this_thread::sleep_for(std::chrono::milliseconds(static_cast<long long>(pause.asMilliseconds())));
}
}while(ret != 0 && clock.getElapsedTime() < timeout);
Expect(ret == 0, Throw(InternalError, "Failed to connect to the remote host"));
