Description

When the device runs as a Archived:Wireless Information Sharing Engine server there is a need to stop the service after a timeout period if no client connects before it.

The waiting is done syncronously with the Maemo Platform and asyncronously with the S60 Platform.

Maemo Platform

int server_start(wise_server* server,int time_out)
{
struct sockaddr_rc client_addr = { 0 };
socklen_t opt = sizeof(client_addr);
char buf[50];
 
struct timeval timeout;
fd_set readfds;
int error;
 
memset(&timeout,0,sizeof(timeout));
timeout.tv_sec = time_out;
timeout.tv_usec = 0;
 
FD_ZERO(&readfds);
FD_SET(server->server_socket,&readfds);
 
/* put server socket into listening mode */
error = listen(server->server_socket,0);
if ( error ) return error;
 
select(server->server_socket+1,&readfds,NULL,NULL,&timeout);
 
if ( FD_ISSET(server->server_socket,&readfds) )
{
/* accept one connection */
server->client_socket = accept(server->server_socket,
(struct sockaddr *)&client_addr,&opt);
ba2str(&client_addr.rc_bdaddr,server->client_address);
server->client_connected = TRUE;
}
else
{
server->client_connected = FALSE;
return WISE_CONNECTION_ERROR;
}
return WISE_OK;
}

S60 Platform

// set to accept incoming connections, active object will handle
iServerSock.Accept(iClientSock,iStatus);
SetActive();
iServerSock.CancelAccept();
