Alfred, thanks for the pointers and the advice and the comments from Joe at
Real.
Its not really a big deal as I do have another route I can use which is
native IPC or I could use the socket functions in the api as well
off to do some more playing .
Its a shame I cannot pull off the events from the IPCSocket but not a major
issue. There are lots of solutions I can use for IPC.
Thanks Again guy's
Mark

First,
when using REALeventInstance, you will need to make sure that your class
inherits from the socket:
REALclassDefinition EcholinkClassDefinition =
{
kCurrentREALControlVersion,
// Version
"iQSO",
// Name
"IPCSocket"
// Super
then
void DataAvailableActionCode(REALobject instance){
printf("HELLO");
}
REALeventInstance EcholinkClassEventInstances[] = {
{ "DataAvailable", (REALproc) DataAvailableActionCode }
};
This way your DataAvailableActionCode gets called. ALso note that you don't
need to use Dynamic access to instantiate the socket, because in the RB
runtime you can simply do new IQSO.
My guess though is that you don't want to use this avenue, and there is no
official API to install an eventhandler on the IPCSocket. Not sure though
if you can use a dynamic access call to AddHandler, which was introduced
recently. I haven't tried that avenue. Perhaps someone at REAL could shed
some light if AddHandler(REALobject) with the "DataAvailable" signature can
by successfully accessed...
