The disadvantages of socketpair() method: 1. It require tcp/ip to be installed. B19 can run on computers without tcp/ip installed. 2. B19 implements loading of wsock32.dll on demand to speed-up process startup about 20%. With socketpair() every running process will load wsock32.dll when tty support is enabled. The toolset will run _slower_ than now with pipe polling. -- Sergey Okhapkin, http://www.lexa.ru/sos Moscow, Russia Looking for a job - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
