stealIn

---

pipe_t Pipe::stealIn()

Steals ownership of the in pipe outside of the Pipe class.

Resets the pipe value to zero. Caller is responsible for closing the pipe.

stealOut

---

pipe_t Pipe::stealOut()

Steals ownership of the out pipe outside of the Pipe class.

Resets the pipe value to zero. Caller is responsible for closing the pipe.
