CHAIN(3)						 MBK UTILITY STRUCTURE DEFINITIONS						  CHAIN(3)

NAME

       chain - mbk lisp-like service structure

DESCRIPTION

       The chain is used for any purpose, when a list of pointer is required.  The use of this structure is strongly recommanded, when such a need
       occurs.

       The declarations needed to work on chain are available in the header file "/labo/include/mut315.h", where '315' is the actual mbk version.

       The following C structure supports the description of the chain :
	      typedef struct chain {
		 struct chain	  *NEXT;
		 void		  *DATA;
	      } chain_list;

       NEXT		   Pointer to the next chain of the list.

       DATA		   Generic pointer used to point to any kind of object. Do not forget to cast the pointer back to its previous	type  when
			   using this field.

       Remark : 	   a  specialized memory allocator has been built in order to create and free chain_lists, so absolutly avoid to create or
			   free them an other way than through the access functions.
