Declaration [src]
gboolean
g_ptr_array_find_with_equal_func (
GPtrArray* haystack,
gconstpointer needle,
GEqualFunc equal_func,
guint* index_
)
Description [src]
Checks whether needle exists in haystack, using the given equal_func.
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.
equal_func is called with the element from the array as its first parameter,
and needle as its second parameter. If equal_func is NULL, pointer
equality is used.
