void *lv_utils_bsearch(const void *key, const void *base, size_t n, size_t size, int (*cmp)(const void *pRef, const void *pElement))
Searches base[0] to base[n - 1] for an item that matches *key.
Note
The function cmp must return negative if it's first argument (the search key) is less that it's second (a table entry), zero if equal, and positive if greater.
Note
Items in the array must be in ascending order.
- Parameters:
key -- Pointer to item being searched for
base -- Pointer to first element to search
n -- Number of elements
size -- Size of each element
cmp -- Pointer to comparison function (see unicode_list_compare() as a comparison function example)
- Returns:
a pointer to a matching item, or NULL if none exists.
