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 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},
       };

X Version 11		Release 6.4				1

XtSetArg(3Xt)		XT FUNCTIONS		XtSetArg(3Xt)

       XtSetValues(Widget, args, XtNumber(args));

       Note that you should not use auto-increment or auto-decre-
       ment 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.
