NAME

       reallocate_resource - allocate a slot in the resource tree given range & alignment. The resource will be relocated if the new size cannot
       be reallocated in the current location.

SYNOPSIS

       int reallocate_resource(struct resource * root, struct resource * old, resource_size_t newsize, struct resource_constraint * constraint);

ARGUMENTS

       root
	   root resource descriptor

       old
	   resource descriptor desired by caller

       newsize
	   new size of the resource descriptor

       constraint
	   the size and alignment constraints to be met.

Name
  XtGetConstraintResourceList - get the constraint resource list structure for a particular widget class.

Synopsis
  void XtGetConstraintResourceList(object_class, resources_return, num_resources_return)
	   WidgetClass object_class;
	   XtResourceList *resources_return;
	   Cardinal *num_resources_return;

Inputs
  object_class	 Specifies the object class to be queried; may be of class objectClass or any subclass thereof.

Outputs
  resources_return
		 Returns the constraint resource list.

  num_resources_return
		 Returns the number of entries in the constraint resource list.

Availability
  Release 4 and later.

Description
  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.

Usage
  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().
