{
Timespan timeout(250000);
EchoServer echoServer;
StreamSocket ss;
ss.connect(SocketAddress("localhost", echoServer.port()));
Socket::SocketList readList;
Socket::SocketList writeList;
Socket::SocketList exceptList;
readList.push_back(ss);
assert (Socket::select(readList, writeList, exceptList, timeout) == 0);
assert (readList.empty());
assert (writeList.empty());
assert (exceptList.empty());
ss.sendBytes("hello", 5);
ss.poll(timeout, Socket::SELECT_READ);
readList.push_back(ss);
writeList.push_back(ss);
assert (Socket::select(readList, writeList, exceptList, timeout) == 2);
assert (!readList.empty());
assert (!writeList.empty());
assert (exceptList.empty());
char buffer[256];
int n = ss.receiveBytes(buffer, sizeof(buffer));
assert (n == 5);
assert (std::string(buffer, n) == "hello");
ss.close();
}示例2: testNonBlocking
void SocketTest::testNonBlocking()
{
