XtSetArg(3)			 XT FUNCTIONS			   XtSetArg(3)

NAME
       XtSetArg, XtMergeArgLists - set and merge ArgLists

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

       ArgList XtMergeArgLists(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 com-
       bined 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.
