hi, I`m doing an application where I use sockets to connect two
differentes machines, but I don`t know how to create the buffers to
receive and to send data

an "array of char" will do. In fact, you can use a std::vector<char>
and size it to the size you want to read (or more).

you define a structure , and set value to the member of this object of
structure,and write code like
"send(s,&your_object_of_structure,sizeof(your_obje ct_of_structure),0)"

It all depends on what you plan on doing with the buffer. If you plan on
filling it, then passing it to something else, a std::string should be fine.
If you need to buffer messages by some code or something, maybe a
std::vector<std::string>.

A lot of it just depends.

There is also std::queue, and std::streambuf, the first can be used
direct as a fifo container or as an interface example for say a fixed
size buffer using an array. The second may provide a base class for
the interface for a buffer.


I think Boost.Asio covers this sort of ground, so may be worth
investigating too:

That said I have never had much dealings with any of the above...
