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);
}
SEE ALSO¶
mbk(1),
chain(3).
