destruct objects

[amitk3553]

Hello,

 

I have to reset the fifo, I was doing like that cmd_fifo.nb_read(Flush), currently need to read each location to reset the whole fifo, So I want to know is there any method like cmd_fifo.reset() or we can destroy the object as done below?

 

sc_fifo<int> cmd_fifo;

 

SC_CTOR()

{

   host_hci_tar_socket.register_b_transport(this, (&hci_top::PI_decode));

}

 

void PI_decode()

{

   if(value==1)

   {

     ~cmd_fifo();           //destructor

   }

}

 

I used destructor like above but its not working, so suggest something about this.

 

 

Regards

Hello Sir,

May we request that you get a good reference book on C++ and read it up ?

The destructor for a class is ALWAYS placed inside the class, for example:

class foo

{

 foo(){}

~foo(){} /* destructor */

};

Most importantly, a destructor is NEVER, EVER invoked by the programmer.

A destructor is invoked ONLY by the runtime system when the instance of a

class(the object) is destroyed.

Hope that helps.

The methods of sc_fifo are described in the LRM, see section 6.23.2.

 

If you look at that, there are no functions for clearing a fifo. However it would be quite easy to write a helper function, e.g.

void function reset_fifo (sc_fifo<int> & f) {
    int dummy;
     while ( f.nb_read(dummy) )
         ;
}

P.S. Making it a template function is left as an exercise for the reader :-)

Yes, I had Implemented in the same way as you said.

But I was looking for some inbuilt function or something else to reset the fifos to reduce my code.

k, its fine.

 

Thanks
