find
Description:
Checks whether needle exists in haystack.
If the element is found, true is returned and the element’s index is returned in index_ (if
non-null). Otherwise, false is returned and index_ is
undefined. If needle exists multiple times in haystack, the index of the first instance is returned.
This does pointer comparisons only. If you want to use more complex equality checks, such as string comparisons, use find_with_equal_func.
Parameters:
| needle |
pointer to look for |
| haystack |
pointer array to be searched |
| index_ |
return location for the index of the element, if found |
Returns:
|
true if |
