NAME top

       open_init_pty - run an program under a pseudo terminal

SYNOPSIS top

       open_init_pty SCRIPT [[ARGS]...]

DESCRIPTION top

       Run a program under a pseudo terminal. This is used by run_init to
       run actually run the program after setting up the proper context.
       This program acquires a new Pseudo terminal, forks a child process
       that binds to the pseudo terminal, and then sits around and
       connects the physical terminal it was invoked upon with the pseudo
       terminal, passing keyboard input into to the child process, and
       passing the output of the child process to the physical terminal.

       It sets up the pseudo terminal properly based on the physical
       terminal attributes, and then sets the user's terminal to RAW
       mode, taking care to reset it on exit.
