No powerpoint in linux ;-) lol

we are lucky!

You have Impress with OpenOffice. Although I'm not sure if there is a tool specific to Powerpoint that you're doing UML in?

No specific tool. I make what I want. I'm a ol' boy that predates formal UML, thus have no problems.

You can use Dia in linux.

OK! I'm back :-)!

I followed your advices and I wrapped the network functions.

Now, I would like to do clean job. I'm currently working on my Network class. Now, I have a class containing the following functions :

(Toggle Plain Text)

class cNetwork
{
	cnetwork();
	cnetwork(int port);
	~cnetwork();
	void send_to(char *buffer,int length);
	int receive_from(char *buf,int buf_size);
	void bind_to(void);
	void wait_connection(void);
};

I think it should be a good thing to separate the server functions of the generic ones ("send_to"/"receive_from") and I should add a "connect_to" one.

When I have a server, if I accept a connection, a new socket number is created, so I need to have 2 socket variable in the class. It's not needed when I have to use a client connection. So, I would like to build the following inheritance of class:

parent : cNetwork (containing the socket and receive_from / send_to functions)
childrens :

cNetwork_server (containing the bind, accept...)

cNetwork_client (containing the connect and other usefull functions to search the dns etc...)

This mean the cNetwork_server class need to access to the socket variable of the parent class. Is this a good practice to use ?
Can you see another way to do this ? Any advice ???

Here the code of the class to be sure everybody can understand what I would like to do:

(Toggle Plain Text)

class cNetwork
{
public:
    cNetwork();
    ~cNetwork();
    void send_to(char *buffer,int size);
    int receive_from(char *buffer,int size);
protected:
    int socket;
};

class cNetwork_server : cNetwork
{
    /* I must use the variable socket of the parent class withing the functions of this class */
    cNetwork_server();
    ~cNetwork_server();
    void bind_to();
    void wait_for_connection();
};

class cNetwork_client : cNetwork
{
    /* I must use the variable socket of the parent class withing the functions of this class */
     cNetwork_client();
     ~cNetwork_client();
     void connect_to();
};

thank you for your precious help!
