Thread: Invalid conversion from 'const void*' to 'void*' error

Thanks for your response.

It makes sense to me that have to match so I have changed the printname and ListInsert to use a const void * type and that elimated the errors but created a new one in ListInsert function.

Here is the code for that.

Code:

bool ListInsert(List *l, Position p, const void *item) {
    ListNode *tmp;

    tmp = (ListNode *)malloc(sizeof(ListNode));
    if (tmp == NULL) {
        return false;  // No memory
    }
    tmp->item = item;
    if (p == NULL) { // insert at head
        tmp->next = l->head;
        l->head = tmp;
    }
    else {
        tmp->next = p->next;
        p->next = tmp;
    }
    return true;
}

The line reporting the error is

Code:

tmp->item = item;

would this mean i would need to change void *item to const void *item

I think I am a bit stumped on the usage of const.

Thanks Again for you help.
