示例1: constructing
void tst_QTcpServer::constructing()
{
QTcpServer socket;
// Check the initial state of the QTcpSocket.
QCOMPARE(socket.isListening(), false);
QCOMPARE((int)socket.serverPort(), 0);
QCOMPARE(socket.serverAddress(), QHostAddress());
QCOMPARE(socket.maxPendingConnections(), 30);
QCOMPARE(socket.hasPendingConnections(), false);
QCOMPARE(socket.socketDescriptor(), -1);
QCOMPARE(socket.serverError(), QAbstractSocket::UnknownSocketError);
// Check the state of the socket layer?
}示例2: createListeningSocket
int ServerManager::createListeningSocket(const QHostAddress &address, quint16 port)
{
int sd = 0;
QTcpServer server;
if (!server.listen(address, port)) {
qCritical("listen failed");
return sd;
}
sd = ::fcntl(server.socketDescriptor(), F_DUPFD, 0);
#if defined(FD_CLOEXEC)
::fcntl(sd, F_SETFD, 0);
#endif
server.close();
return sd;
}示例3: nativeListen
/*!
Listen a port for connections on a socket.
This function must be called in a tfmanager process.
*/
int TApplicationServerBase::nativeListen(const QHostAddress &address, quint16 port, OpenFlag flag)
{
int sd = 0;
QTcpServer server;
if (!server.listen(address, port)) {
tSystemError("Listen failed port:%d", port);
return sd;
}
sd = duplicateSocket(server.socketDescriptor()); // duplicate
if (flag == CloseOnExec) {
::fcntl(sd, F_SETFD, ::fcntl(sd, F_GETFD) | FD_CLOEXEC);
} else {
::fcntl(sd, F_SETFD, 0); // clear
}
::fcntl(sd, F_SETFL, ::fcntl(sd, F_GETFL) | O_NONBLOCK); // non-block
