/* ruby function: getpty */
/*
* call-seq:
* PTY.spawn(command...) {|r, w, pid| ... } => nil
* PTY.spawn(command...) => r, w, pid
* PTY.getpty(command...) {|r, w, pid| ... } => nil
* PTY.getpty(command...) => r, w, pid
*
* spawns the specified command on a newly allocated pty.
*
* The command's controlling tty is set to the slave device of the pty.
* Also its standard input/output/error is redirected to the slave device.
*
* PTY.spawn returns two IO objects and PID.
* PID is the process ID of the command.
* The two IO objects are connected to the master device of the pty.
* The first IO object is opened as read mode and
* The second is opened as write mode.
*
* If a block is given, two IO objects and PID is yielded.
