現(xiàn)象：QUdpSocket bing ip加端口失敗

//bool tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port );//失敗?

//? ? QString string("192.168.112.10");

//? ? QHostAddress address(QHostAddress::LocalHost);//QHostAddress::Any

//? ? bool tf =address.setAddress( string );

//? ? tf =m_pSocket->bind(address,m_port );//失敗

//? ? quint32 ip4Add = 192<<24|168<<16|112<<8|10;

//? ? QHostAddress address(QHostAddress::Any);//QHostAddress::LocalHost

//? ? address.setAddress( ip4Add );

//? ? bool tf =m_pSocket->bind(address,m_port );//失敗

改為：如下都可以， 只是增加了一個(gè) 選項(xiàng)， 默認(rèn) 的0 幫助文檔說(shuō)在window上是ShareAddress ， 但是不其作用， 需要

quint32 ip4Add = 192<<24|168<<16|112<<8|100;

? ? bool tf =m_pSocket->bind(QHostAddress(ip4Add),6000,QAbstractSocket::ShareAddress );

? ? tf =m_pSocket->bind(QHostAddress(ip4Add),6000,QAbstractSocket::ReuseAddressHint| QAbstractSocket::ShareAddress | QAbstractSocket::DontShareAddress );

? ? //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6001,QAbstractSocket::ReuseAddressHint| QAbstractSocket::ShareAddress | QAbstractSocket::DontShareAddress );//失敗

? ? //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6002,QAbstractSocket::ReuseAddressHint );

? ? //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6003,QAbstractSocket::ShareAddress? );

? ? //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6004,QAbstractSocket::DontShareAddress );

? ? tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6005,QAbstractSocket::ReuseAddressHint | QAbstractSocket::ShareAddress? );

? ? tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6006,QAbstractSocket::DontShareAddress | QAbstractSocket::ReuseAddressHint? );

? ? tf =m_pSocket->bind(QHostAddress("192.168.112.100"),6007,QAbstractSocket::DontShareAddress | QAbstractSocket::ShareAddress? );
