SYNOPSYS

       #include "mut.h"
       chain_list *reverse(ptold)
       chain_list *ptold;

PARAMETER

       ptold		   Pointer to a chain_list to be reversed

DESCRIPTION

       The reverse function allows to reverse the order of the elements of a chain_list. It means that the last element becomes the first one, the
       one before the last one the second one, and so on.

       remark :
	      all  mbk	structures have for first field the NEXT field, so, with appropriate cast, one can reverse any mbk list. Let's notice that
	      nothing in the C language description demands a structure to be defined in memory the same way its members are defined in C. But all
	      compiler do it this way now a day.  Let's hope it will continue!

RETURN VALUE

       reverse returns a pointer to the head of the reversed list.

EXAMPLE

       #include "mut.h"
       void reverse_con(p)
       lofig_list *p;
       {
	  p->LOCON = (locon_list *)reverse((chain_list *)p->LOCON);
       }
