Question

my question is how do I assign the smart pointer to the other ? I am not sure how to get around the temporary variable either ?

typedef boost::asio::ip::tcp::socket            TBoostSocket;
typedef boost::shared_ptr<TBoostSocket>        TSocket;

TSocket createSocket(const IpcNode::TPath& a_path) {

    TSocket socket(new TBoostSocket(*this->getIoservice()));
    return socket;

}

//in another function

TSocket result();

result= createSocket(a_path);

// compiler output
error: taking address of temporary [-fpermissive]

41: error: assignment of function ‘IPC::TcpServices::TSocket IPC::result()
cannot convert ‘TSocket* {aka boost::shared_ptr >*}’ to ‘TSocket() {aka boost::shared_ptr >()}’ in assignment

I know I am missing something obvious I just can see it right now

Answer 1

The following declares a function (that takes no arguments and returns TSocket):

TSocket result();

Change it to:

TSocket result;
