in reply to perl -Dusethreads compilation

Also, Major part of my code deals with using Net::FTP in threads, does anyone know if I should use semaphores with it?

What would you use the semaphores for? (Ie. Why do you think you might need to use semaphores?)

      Which critical blocks of code?

      (This would go a lot quicker of you gave us some clue as to what you are trying to do! Ie. Post your code, or at the very least, some pseudo-code of what you're intending to do. As is, your question is impossible to answer.)

# create n numbers of threads
  #create ftp connection/login
  while (1)
  { wait msg Q();
    1. dequeue element
    2. download file from ftp server.
    3. delete file.
  }

# Master Thread
#create ftp connection/login
  while (1)
  { if 'files exist on ftp server'
    {
      enqueue files to download
    }
  }

        [download]

        To sum it, master threads gets list to download files and workers just downloads the file.

        I am worried about multiple threads colliding, race condtions, in NET::FTP module.
