Problem with vectors

Hi,

I've just started using vectors. I've decided to use one to hold connection info for incoming client connections in my program.

However, VC++ fails to compile at the "v_clients::iterator i;" line in build_fdset with this error:

Error C2510: 'v_clients' : left of '::' must be a class/struct/union

I understand this error, but I can't seem to work out where I've gone wrong. I've got a feeling it's going to be something obvious, but I can't find it =)

Here's the pieces of relevant code cut out and put together:

Code:

#include <vector>
#include <winsock2.h>

using namespace std;

typedef struct
{
  struct sockaddr_in sin;
  SOCKET sock;
} cnx_inf;

typedef vector<cnx_inf> cnx_inf_vector;

cnx_inf_vector v_clients;

void build_fdset(fd_set *fds, SOCKET sock_Serv)
{
	v_clients::iterator i;

	FD_ZERO(fds);
	FD_SET(sock_Serv,fds);
	
	for (i = v_clients.begin(); i != v_clients.end(); i++)
    {
         FD_SET(*i.sock,fds);
    }
}

Any help greatly appreciated.

Many thanks,

Daniel

its been a while but i think it should be

cnx_inf_vector::iterator i;

Code:

cnx_inf_vector::iterator i;

Thanks guys

Record time, fixed within 6 minutes

I've got another problem related to the same code.

The line

Code:

 FD_SET(*i.sock,fds);

throws an error (which is rather long), basically telling me that *i.sock is not valid. How can I get to the member variables of the struct in each element of the vector?

Many thanks,

Daniel

Forget it, I eventually found the answer I was looking for after doing several searches.

Don't leave a thread hang'n.....

Readers of this thread might benefit from the answer you found as well.

It should have been: (*i).sock

The member operator has higher precedence than the dereference operator so you have to use parens to make sure the dereference is done first.
