NAME

     pktDest - Packet Dest Object



SYNOPSIS

     pktDest prefix ?options?



DESCRIPTION

     The pktDest command creates a new packet dest  object,  used
     to  receive  data  using  the  cyclic-UDP  protocl.   For  a
     detailed description of the protocol,  which  is  useful  in
     understanding  the  various configuration slots and how they
     affect the behavior of the packet objects, see [Smith 94].

     The name of the new object (which is created by appending  a
     unique suffix to prefix) is returned.  This name is also the
     name of a Tcl command that can be used  with  the  following
     options.


OPTIONS

  object destroy
     Destroys the packet dest named object.

  object address
     Returns the local hostname and port number on  which  object
     is listening.

  object configure ?-options?
     Sets configuration parameters  for  object.   Valid  options
     are:

          -outCmd
               Where to send data as it arrives.  This should  be
               a string conforming to the usual CMT semantics for
               passing data between objects.  That is, it  should
               be either the name of a Tcl procedure to be called
               every time data is available, or a string  of  the
               form  @object.accept  where  object  is  some  CMT
               object that will accept the data.

          -shared
               A boolean value, indicating  whether  the  buffers
               used  by object should be shared memory buffers or
               not.

          -attach
               A boolean value, indicating  whether  the  buffers
               used  by object should be attached to the X server
               or not.

          -address
               The host name and port number on which  object  is
               listening.
