Good hosting? For geting and sending positions?

See fourth reply. (Mine)
For what I need help with.

Ya know, I noticed that when you accept you put it in a socket of it's own. Maybe if I put those in an array, I could go and check each one.......

Am I on the right track with that?



I have this so far:

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <AzjSock.h>

class socketinfo{
public:
SOCKET sock;
int SendBytes;
int RectBytes;
};




int main(int argc, char *argv[])
{
char* buff;   

WSA2S();

SOCKET server;
server = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);


SOCKADDR_IN sinServer;
memset(&sinServer, 0, sizeof(sinServer));
sinServer.sin_family = AF_INET;
sinServer.sin_addr.s_addr = INADDR_ANY; // Where to start server?
sinServer.sin_port = htons(PORT); // Port
       
if(bind(server, (LPSOCKADDR)&sinServer, sizeof(sinServer)) == SOCKET_ERROR){ easymsg("Couldn't bind."); }


int numclients = 0;
socketinfo clients[9];

if(listen(server,9)){ easymsg("Listen failed."); }
ioctlsocket(server, FIONBIO, &iMode);

FD_SET Writer;
FD_SET Reader;
   
   
while (true){
FD_ZERO(&Reader);
FD_ZERO(&Writer);

FD_SET(server, &Reader);



for(int o = 0; o<numclients; o++)
{
//if(clients[o].RectBytes > clients[o].SendBytes){ FD_SET(clients[o].sock,&Writer);
//} else{ FD_SET(clients[o].sock,&Reader);
//}
FD_SET(clients[o].sock,&Reader);
}




if(select(0,&Reader,&Writer,NULL,NULL))
{

if(FD_ISSET(server,&Reader)){
 
SOCKET ATemp;

if((ATemp = accept(server,NULL,NULL)) != INVALID_SOCKET){
numclients++;
clients[numclients].sock = ATemp;
ioctlsocket(clients[numclients].sock,FIONBIO,&iMode);
clients[numclients].SendBytes = 0;
clients[numclients].RectBytes = 0;
cout<<"Accepted a client.\nNow up to "<<numclients<<" clients.\n";
       
}               
}








for (int i = 0; i<numclients; i++)
{


recv(clients[i].sock,buff,sizeof(buff),0);
cout<<"Recived: "<<buff<<"\n";


}






}
    Sleep(5);
}   



closesocket(server);
WSACleanup();
}

It can accept connections and SHOULD be able to recive.

What you really need to look into is either the use of threads and as you have already mentioned, the function select().

Also, do you have a specific problem?

You also should be checking the return of your calls to send and recv, or else you may be dealing with incomplete or corrupted data.

Also for a cosmetic tip, please indent your code. I(and I am sure other posters here) tend to be more helpful when I don't have to struggle to read code.

Atm my problem is that it's not reciving and it should.

I'd also like to add...

I made this program... it crashes... why?

Code:

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <AzjSock.h>

class socketinfo{
public:
SOCKET sock;
WSABUF DataBuf;
bool isused;
int SendBytes;
int RectBytes;
};




int main(int argc, char *argv[])
{
char* buff;   

WSA2S();

SOCKET server;
server = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);


SOCKADDR_IN sinServer;
memset(&sinServer, 0, sizeof(sinServer));
sinServer.sin_family = AF_INET;
sinServer.sin_addr.s_addr = INADDR_ANY; // Where to start server?
sinServer.sin_port = htons(PORT); // Port
       
if(bind(server, (LPSOCKADDR)&sinServer, sizeof(sinServer)) == SOCKET_ERROR){ easymsg("Couldn't bind."); }


int numclients = 0;
socketinfo clients[9];

for(int uu = 0; uu<9; uu++){
clients[uu].isused = false;
}

if(listen(server,9)){ easymsg("Listen failed."); }
ioctlsocket(server, FIONBIO, &iMode);

FD_SET Writer;
FD_SET Reader;
   
   
while (true){
FD_ZERO(&Reader);
FD_ZERO(&Writer);

FD_SET(server, &Reader);



for(int o = 0; o<numclients; o++)
{
//if(clients[o].RectBytes > clients[o].SendBytes){ FD_SET(clients[o].sock,&Writer);
//} else{ FD_SET(clients[o].sock,&Reader);
//}
FD_SET(clients[o].sock,&Reader);
}




if(select(0,&Reader,&Writer,NULL,NULL))
{

if(FD_ISSET(server,&Reader)){
 
SOCKET ATemp;

if((ATemp = accept(server,NULL,NULL)) != INVALID_SOCKET){
numclients++;
clients[numclients].sock = ATemp;
ioctlsocket(clients[numclients].sock,FIONBIO,&iMode);
clients[numclients].SendBytes = 0;
clients[numclients].RectBytes = 0;
clients[numclients].isused = true;
cout<<"Accepted a client.\nNow up to "<<numclients<<" clients.\n";
       
}               
}








for (int i = 0; i<numclients; i++)
{
if (clients[i].isused == true)
{

if (FD_ISSET(clients[i].sock, &Reader))
{

cout<<"Stuff.\n";
clients[i].DataBuf.len = 256;
clients[i].DataBuf.buf = buff;
DWORD Flags; 
DWORD Rec;                             
WSARecv(clients[i].sock, &(clients[i].DataBuf), 1,&Rec, &Flags, NULL, NULL);

char* bob = new char[clients[i].DataBuf.len];
bob = clients[i].DataBuf.buf;

cout<<"Recived: "<<bob<<"\n";

}

}
}






}
    Sleep(5);
}   



closesocket(server);
WSACleanup();
}

It crashes due to a lack of indentation. Fix that, then we'll pursue any remaining problems.

Okay, here it is, indented:

Also...

My timeval dosn't work...

Code:

---

struct timeval tv;
tv.tv_sec = 10;
tv.tv_usec = 500000;

---

Anything wrong with it? Cause it makes compiler errors.

Here is my newest code, it almost works:

I indented it again.

There are olny two things wrong with it now.....
1. It keeps repeating "Recived: " MESSAGEHERE until something else is recived.
2. It won't recive until someone new connects.


(And I did Indent it)
