NAME
reverse - reverse a list of chained elementsSYNOPSYS
#include "mut.h" chain_list ∗reverse(ptold) chain_list ∗ptold;PARAMETER
ptold Pointer to a chain_list to be reversedDESCRIPTION
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 descrip‐ tion 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 con‐ tinue!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
