<hr><a name="_details"></a><h2>Detailed Description</h2>
This structure stores information about message events.
<p>
A message event is a command, specified by the command field, together with one of several additional pieces of information, ranging from a single byte of data to a generic pointer.
<p>
This arrangement allows for great flexibility when TVision objects need to transmit and receive messages to and from other TVision objects. <dl compact><dt><b>See also: </b></dt><dd>

I suggest you to pay attention to these fields. Use always the same type in the sender and in the receivers of the message. Otherwise you may experiment portability problems.
