If we look at the definition below:
struct string_list {
struct string_list_item *items;
unsigned int nr, alloc;
unsigned int strdup_strings:1;
compare_strings_fn cmp; /* NULL uses strcmp() */
I think a simple memset() will be easier to read,
and it will be more future proof:
In case elements are added, the will have 0 or NULL automatically:
void string_list_init_nodup(struct string_list *list)
{
memset (list, 0, sizeof(*list));
}
(But then I wonder if we need the function at all ?)
Or does it make sense to have a common function similar to this,
which covers both cases:
void string_list_init(struct string_list *list, int strdup_strings)
{
memset (list, 0, sizeof(*list));
list->strdup_strings = strdup_strings;
}
