Timeout for recv() ?

[AndyTheAce]

Hi Folks,

I've written a multithreaded server application with the following problem:

On a client connect, a new thread will start.
Clients will send a pingsignal for validating server accessibility, the other way arround I want to have something like a timeout for the server.

If for example no data is received for 1 minute, the server should drop that client. Code looks like this:

do {
  		rec=recv(ss,buffer,BUFLEN,0);
  		if(rec>0){
			printf("Thread %u (%s): - received bytes: %d\n", pid, remoteaddr, rec);
		}
		else if(rec==0){
			sprintf(errormsg,"Thread %u:\Connection was closed. %s(%s)\n\n",pid,remoteaddr,data->h_name);
   			printf(errormsg);
			error = TRUE;
   			break;
  		}
		else{
			printf("Thread %u (%s): error while reading(recv()): %d\nConnection interrupted.\n", pid, remoteaddr, WSAGetLastError());
		}

    // cut
	
   		memset(buffer,0,BUFLEN);		
 	}while(rec>0);

with that code, the server thread won't detect if a client hang, crashes or just reboot.

So now my question, can I setup a timeout for recv() or have I to do this on my own with some kind of timer?

Thanks in Advance,
Andy
