程序大致如下，现在出现的问题是在完成长连接之后，多次的收发数据，大概几百次左右sl_Send就会返回负值，报ERR_PRINT(SEND_ERROR);3次后跳出while，程序重新建立socket，这一次还重新能跑回sl_Send那，收发一次成功之后，会再出现sl_Send返回负值，跳出while,再重新建立socket就会在sl_bind上一直报错，ERR_PRINT(BIND_ERROR);我看过它的返回值iStatus是-99，也就是SL_EADDRNOTAVAIL这个错误。我整个程序就这里使用了g_GateWayInfo.TCP_iport这个端口，为什么会出现EADDRNOTAVAIL的错误呢？然后我现在要怎么解决这个问题？
