Hi,

does anyone know how to listen on a server socket (ISocket-listen) and on the same time listen for other signals like CTRL-C.

I'm looking for something like ISocket->WaitSelect but for a server implementation.

regards

max

I figured it out by myself. If somebody wants to know how to do it. You can actually use ISocket->WaitSelect for implemneting a simple server like this (simplified, no error checking etc):


ISocket->bind( socket,(struct sockaddr *)&addr,sizeof(addr) );

ISocket->listen( socket,1 )



for( int loop = TRUE;loop; ) {

  fd_set listenFds;

  FD_ZERO( &listenFds );

  FD_SET( socket,&listenFds );



  printf("Listening.....\n");

  ULONG signals = SIGBREAKF_CTRL_C;

  int readyDescriptors = ISocket->WaitSelect( socket +1,&listenFds,NULL,NULL,NULL,&signals );



  if( readyDescriptors == -1 ) {

    printf( "Network Error.\n" );

    loop = FALSE;

  } 

  else {

    if( ( signals & SIGBREAKF_CTRL_C ) == SIGBREAKF_CTRL_C ) {

      printf( "Detected CTRL-C.\n" );

      loop = FALSE;

    }



    if( FD_ISSET( socket,&listenFds ) ) {

      int client = ISocket->accept( socket,NULL,NULL );

      if( client != -1 ) {

        printf("Client connected.\n"); 

        ISocket->CloseSocket( client );

      }

    }

  }

}
