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.
