     XtSetArg(3Xt)                                  XtSetArg(3Xt)



     NAME
          XtSetArg, XtMergeArgLists - set and merge ArgLists

     SYNOPSIS
          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 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 address.

     DESCRIPTION
          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},



                                - 1 -

     XtSetArg(3Xt)                                  XtSetArg(3Xt)



               {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 twice.

          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.
