Re: returning a data member's address - how?

I see what you mean about perhaps breaking encapsulation
here. Maybe I'm designing this the wrong way. I'll tell you
my reasons - the code on my system which deals with IP
clients/servers is written in C. The function available to
me on my system to connect from a socket accepts as
arguments:

1. a pointer to the start of the IPaddress
2. an IPaddress+port length

The IPaddress and Port variables (not the actual names I
used, but you get the idea) are held in a C struct called
Socket (for argument's sake).

I don't have the expertise or access rights to change the
function or write my own in C++, so I'm stuck with that. I
did, however, fancy at least writing my own Socket class to
hold the data members. I'm a relative newbie at this and
enjoy the practice. So anyway, I have the class written, and
it contains accessor methods to Get (but not set) the
address of the IPAddress member and the combined
IPAddress+port length. Feed them into the C function, and it
should work just as if I were using a C struct to hold the
data, is the theory (yet to be tested). However, I'm
wondering if the better course might be to just use the C
struct for the job at hand, and regard my class as a
learning exercise, if I'm breaking encapsulation by
providing the address of a data member. Ho hum.
