To check whether an address is free or not it is enough to check the address equals to NULL.
linkedList == NULL
since you are using free(linkedList) it should be okay.
Question
#include <stdio.h>
typedef struct _person
{
char name[64];
char gender[2];
struct _person * pNext;
struct _person * pPartner;
} PERSON_T;
typedef struct
{
PERSON_T * head;
PERSON_T * tail;
PERSON_T * current;
} LIST_T;
I have the struct and then i free like this
void freestruct(LIST_T *linkedList)
{
linkedList->current = linkedList->head;
if (linkedList != NULL) /* if list has been initialized */
{
PERSON_T * pThisItem = linkedList->head;
while (pThisItem != NULL)
{
PERSON_T * pNext = pThisItem->pNext;
free(pThisItem);
pThisItem = pNext;
}
free(linkedList);
}
}
How i can check that its free or not beacuse i dont know the functionfree that i made it right or not.
sorry about my english
Thank you.
