You could do something similar to qsort(3):

void qsort(void *base, size_t nmemb, size_t size,
           int(*compar)(const void *, const void *));

The profile would be something like (returning the number of elements in
the new array, assuming in-place editing of the array):

size_t nub(void *base, size_t nmemb, size_t size,
           int(*compar)(const void *, const void *));
