function returning an ip address

pert · May 29, 2018, 1:40pm

Just in case some official, long-established, real-world examples of returning an IPAddress from a function are needed:

arduino-libraries/Ethernet/blob/1.1.2/src/Ethernet.cpp#L104-L129


      
          IPAddress EthernetClass::localIP()
          {
            IPAddress ret;
            SPI.beginTransaction(SPI_ETHERNET_SETTINGS);
            W5100.getIPAddress(ret.raw_address());
            SPI.endTransaction();
            return ret;
          }
          
          
IPAddress EthernetClass::subnetMask()
          {
            IPAddress ret;
            SPI.beginTransaction(SPI_ETHERNET_SETTINGS);
            W5100.getSubnetMask(ret.raw_address());
            SPI.endTransaction();
            return ret;
          }
          
          
IPAddress EthernetClass::gatewayIP()
          {
