XtSetArg(3Xt)                 SDK X11 R4.11MU05                XtSetArg(3Xt)


NAME
       XtSetArg, XtMergeArgLists - set and merge ArgLists

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

       ArgList XtMergeArgLists(args1, numargs1, args2, numargs2)
            ArgList args1;
            Cardinal numargs1;
            ArgList args2;
            Cardinal numargs2;

ARGUMENTS
       arg       Specifies the name-value pair to set.

       args1     Specifies the first ArgList.

       args2     Specifies the second ArgList.

       numargs1 Specifies the number of arguments in the first argument
                 list.

       numargs2 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.
