* NAME
*	Pointer Vector
*
* DESCRIPTION
*	The Pointer Vector is a self-sizing array of pointers. Like a traditonal
*	array, a pointer vector allows efficient constant time access to elements
*	with a specified index.  A pointer vector grows transparently as the
*	user adds elements to the array.
*
*	The cl_pointer vector_t structure should be treated as opaque and should be
*	manipulated only through the provided functions.
*
* SEE ALSO
*	Structures:
*		cl_ptr_vector_t
*
*	Callbacks:
*		cl_pfn_ptr_vec_apply_t, cl_pfn_ptr_vec_find_t
*
*	Item Manipulation:
*		cl_ptr_vector_set_obj, cl_ptr_vector_obj
*
*	Initialization:
*		cl_ptr_vector_construct, cl_ptr_vector_init, cl_ptr_vector_destroy

/*
* PARAMETERS
*	p_vector
*		[in] Pointer to a cl_ptr_vector_t structure to inititalize.
*
*	pfn_callback
*		[in] Function invoked to determine if a match was found.
*		See the cl_pfn_ptr_vec_find_t function type declaration for details
*		about the callback function.
*
*	context
*		[in] Value to pass to the callback function.
*
* RETURN VALUES
*	Index of the element, if found.
*
*	Size of the pointer vector if the element was not found.
*
* NOTES
*	cl_ptr_vector_find_from_end does not remove the found element from
*	the pointer vector. The index of the element is returned when the function
*	provided by the pfn_callback parameter returns CL_SUCCESS.
*
