XtSetArg(3Xt)               X Version 11(Release 3)               XtSetArg(3Xt)


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 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},
           {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.
