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

       Specifies  the  name-value  pair to set.  Specifies the first ArgList.  Specifies the second ArgList.  Specifies the number of arguments in
       the first argument list.  Specifies the number of arguments in the second argument list.  Specifies the name of	the  resource.	 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.
