Name
       XtSetArg, XtMergeArgLists - set and merge ArgLists

Syntax
       XtSetArg(arg, name, value)
	  Arg arg;
	  String name;
	  XtArgVal value;

       ArgList XtMergeArgLists(args1, num_args1, args2, num_args2)
	  ArgList args1;
	  Cardinal num_args1;
	  ArgList args2;
	  Cardinal num_args2;

Arguments
       arg	 Specifies the name-value pair to set.

       args1	 Specifies the first

       args2	 Specifies the second

       num_args1 Specifies the number of arguments in the first argument list.

       num_args2 Specifies the number of arguments in the second argument list.

       name	 Specifies the name of the resource.

       value	 Specifies the value of the resource if it will fit in an or the address.

Description
       The function is usually used in a highly stylized manner to minimize the probability of making a mistake; for example:

       Arg args[20];
       int n;

       n = 0;
       XtSetArg(args[n], XtNheight, 100);n++;
       XtSetArg(args[n], XtNwidth, 200);n++;
       XtSetValues(widget, args, n);

       Alternatively, an application can statically declare the argument list and use

       static Args args[] = {
	 {XtNheight, (XtArgVal) 100},
	 {XtNwidth, (XtArgVal) 200},
       };
       XtSetValues(Widget, args, XtNumber(args));

       Note that you should not use auto-increment or auto-decrement within the first argument to can be implemented as a macro that dereferences
       the first argument twice.

       The function allocates enough storage to hold the combined structures and copies them into it.  Note that it does not check for duplicate
       entries.  When it is no longer needed, free the returned storage by using
