       XtSetArg, XtMergeArgLists - set and merge ArgLists


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

       ArgList XtMergeArgLists(ArgList args1, Cardinal num_args1, ArgList args2, Cardinal


       arg       Specifies the name-value pair to set.

       args1     Specifies the first ArgList.

       args2     Specifies the second ArgList.

       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 XtArgVal or the


       The XtSetArg 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 XtNumber:

       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
       XtSetArg.  XtSetArg can be implemented as a macro that dereferences the first argument

       The XtMergeArgLists function allocates enough storage to hold the combined ArgList
       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 XtFree.
