CLASS DESCRIPTION
          The VkInput class is an object-oriented interface to Unix pipes.  It
          sets up a pipe, using the VkInput class to provide callbacks to the
          application when input is available.



FUNCTION DESCRIPTIONS
   VkPipe()
           VkPipe(int& fd);
           void ~VkPipe(void);


          Create a non-blocking pipe, setting fd to the write end.  The read
          end is attached to the VkInput object, and the VkPipe::inputCallback
          callback is called when input is available.

   operator[]()
          int operator[](End whichEnd);


          Returns one end of the pipe.  The argument should be READ or WRITE.

DATA MEMBER DESCRIPTIONS
   int[2] pipefd;
          int[2] pipefd;


          Storage of the pipe ends.

   _input;
          VkInput *_input;


          The VkInput object used for the input callback.

VIEWKIT 2.1 CHANGES
   Constructor
           VkPipe(int& fd, VkScreen *screen = NULL);


          this new API is source code compatible with ViewKit 1.5.3 while
          adding a VkScreen option for applications which need to support
          multi-screen connections...
