I have this simple client: 


#include <stdio.h>
#include <X11/Intrinsic.h>
#include <X11/StringDefs.h>
#include <X11/Command.h>

void Quit(w,client_data,call_data)
Widget w;
caddr_t client_data,call_data;

{
	printf("client_data=%s,call_data=%s\n",client_data,call_data);
	exit(0);
}

MyNotify(w,event,params,num_params)
Widget w;
XButtonEvent event;
char *params[];
Cardinal *num_params;
{
	printf("params=%s num_params=%d\n",params[0],*num_params);
	XtCallCallbacks((CommandWidget)w,XtNcallback,(caddr_t)"anything");
}

main(argc,argv)
int argc;
char **argv;
{
	Widget top,cmd;
	static XtActionsRec actions[] = {
			{"myNotify", (XtActionProc)MyNotify},
					 };
	top = XtInitialize( argv[0], "Sample", NULL, 0, &argc, argv);
	cmd = XtCreateManagedWidget("bye",commandWidgetClass,top,NULL,0);
	XtAddActions(actions,XtNumber(actions));
	XtAddCallback(cmd,XtNcallback,Quit,"CLNT DATA");
	XtRealizeWidget(top);
	XtMainLoop();
}

The resource file has this line:
--------------------------------
Sample*bye.translations: #override \n\
	<Btn1Down>: myNotify(Btn1)

=>>THE PROBLEM is, in the function MyNotify(),
printf("params=%s num_params=%d\n",params[0],*num_params);
is not printing anything, because params and the num_params aren't defined!
Why is that? 

I am using X11R3.

Thank you for your help.
