Re: [Quickfix-users] Built QuickFix app, where is the log?

[DA S. A. <ada...@ca...>]

Hi,

1) The logs are in the directory/file you specified into
your conf files :
[DEFAULT]
ConnectionType=initiator
FileStorePath=./store
FileLogPath=./log
............
==> FileLogPath

2) The loop is supposed to wait for something happen
and then exit the application.
In your case you are consuming almost all CPU!
You can put at least a sleep(1second) to avoid CPU
overload, and when something become true/false the loop
exit :
loop = true;
.............
while( loop )
{
    // ......
    // sleep 1 second
    // ......
    if( event == exitEvent )
    {
        loop = false;
    }
}


I use to put waiting on system signals :
..................
for( ; ; )
{
   int signal = wait_for_terminate_request( );
   if( signal == SIGUSR1 )
   {
      break;
   }
   else
   {
      // Do/log something
      // sleep 1 second
   }
}
................

int wait_for_terminate_request( )
{
   sigset_t sset;
   sigemptyset( &sset );
   sigaddset( &sset, SIGINT );
   sigaddset( &sset, SIGQUIT );
   sigaddset( &sset, SIGTERM );
   sigaddset( &sset, SIGUSR1 );
   sigprocmask( SIG_BLOCK, &sset, NULL );
   int sig;
   if( sigwait( &sset, &sig ) == 0 )
      return sig; // Signal number.
   return -1; // Error.
}

In your terminal just type 'kill -10 myappPID'
and it will exit gracefully.

3) Do not 'get' fields directly, you could have exceptions...
You should test if the field is here and then pick it :
if( message.isSetField( FIX::FIELD::ClOrdID ) )
    message.get( clordid );
or for header fields :
if( message.getHeader( ).isSetField( FIX::FIELD::DeliverToCompID ) )
    message.getHeader( ).get( delivertocompid );

Antonio.
