REVERSE(3) MBK UTILITY FUNCTIONS REVERSE(3) NAME reverse - reverse a list of chained elements SYNOPSIS #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); } SEE ALSO mbk(1), chain(3). ASIM/LIP6 October 1, 1997 REVERSE(3)
