NSPipe objects provide an object-oriented interface for accessing pipes. An
NSPipe object represents both ends of a pipe and enables communication through the pipe. A pipe is a one-way communications channel between related processes; one process writes data, while the other process reads that data. The data that passes through the pipe is buffered; the size of the buffer is determined by the underlying operating system.
NSPipe is an abstract class, the public interface of a class cluster.
