XtSetArg(3Xt)			XT FUNCTIONS			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 minim-
  ize 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.
