XtGetResourceList(3)			   XT FUNCTIONS 		     XtGetResourceList(3)

NAME
       XtGetResourceList, XtGetConstraintResourceList - obtain resource list

SYNTAX
       void XtGetResourceList(WidgetClass class, XtResourceList *resources_return, Cardinal
	      *num_resources_return);

       void XtGetConstraintResourceList(WidgetClass class, XtResourceList *resources_return, Car-
	      dinal *num_resources_return);

ARGUMENTS
       num_resources_return
		 Specifies a pointer to where to store the number of entries in the resource
		 list.

       resources_return
		 Specifies a pointer to where to store the returned resource list.  The caller
		 must free this storage using XtFree when done with it.

       widget_class
		 Specifies the widget class.

DESCRIPTION
       If XtGetResourceList is called before the widget class is initialized (that is, before the
       first widget of that class has been created), XtGetResourceList returns the resource list
       as specified in the widget class record.  If it is called after the widget class has been
       initialized, XtGetResourceList returns a merged resource list that contains the resources
       for all superclasses. The list returned by XtGetResourceList should be freed using XtFree
       when it is no longer needed.

       If XtGetConstraintResourceList is called before the widget class is initialized (that is,
       before the first widget of that class has been created), XtGetConstraintResourceList
       returns the resource list as specified in the widget class Constraint part record. If it
       is called after the widget class has been initialized, XtGetConstraintResourceList returns
       a merged resource list that contains the Constraint resources for all superclasses. If the
       specified class is not a subclass of constraintWidgetClass, *resources_return is set to
       NULL and *num_resources_return is set to zero. The list returned by XtGetConstraint-
       ResourceList should be freed using XtFree when it is no longer needed.
