NAME¶

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);
}
