Detailed Description

ipAddrToAsciiEngine is the first class needed to convert an ipAddr to an ASCII address. From the engine, you can use createTransaction() to create a transaction object. The transaction object lets you attach callbacks and convert an address to ASCII.

Example

class ConvertIPAddr: ipAddrToAsciiCallBack
{
     ipAddrToAsciiTransaction & trans;

public:
     epicsEvent complete;

     ConvertIPAddr(ipAddrToAsciiEngine & engine, osiSockAddr & addr):
         trans(engine.createTransaction())
     {
         trans.ipAddrToAscii(addr, *this);
     }

     virtual void transactionComplete (char const * node) override
     {
         printf("Address is %s\n", node);
         complete.signal();
     }

     virtual void show(unsigned level) override const
     {
         printf("This is a ConvertIPAddr class object.");
     }

     virtual ~ConvertIPAddr()
     {
         trans.release();
     }
};

ipAddrToAsciiEngine & engine(ipAddrToAsciiEngine::allocate());

osiSockAddr addr;
addr.ia.sin_family = AF_INET;
addr.ia.sin_addr.s_addr = htonl(INADDR_LOOPBACK);
addr.ia.sin_port = htons(8080);

ConvertIPAddr result(engine, addr);

// Do other work here before waiting on the result

result.complete.wait(2.0);
engine.release();
