XtGetConstraintResourceList - get the constraint resource list structure for a particular widget class.
void XtGetConstraintResourceList(object_class, resources_return, num_resources_return)
object_class Specifies the object class to be queried; may be of class objectClass or any subclass thereof.
Returns the constraint resource list.
Returns the number of entries in the constraint resource list.
Release 4 and later.
XtGetConstraintResources() returns the resource list of the constraintClassPart of the widget class object_class. If it is called before
the widget class is initialized, the resource list as specified in the widget class record will be returned. If it is called after the
widget class has been initialized, the merged resource list for the class and all constraint superclasses is returned. If the specified
object_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 XtGetConstraintResourceList() should be freed using XtFree() when it is no longer needed.
Most applications will never need to query a widget class for the resources it supports. This function is intended to support interface
builders and applications like editres which allow the use to view the available resources and set them interactively.
To get the normal resources of a widget rather than the constraint resources, use XtGetResourceList().
