Question

With an array of a certain type of element. Is there a way to use lfind to retrieve the index of an element instead of a pointer to the element?

Answer 1

You have that with the pointer.

Subtract the start of the array from the returned pointer – that’s the index.

Edit to explain more, just in case:

When you declare an array

int foo[5];

foo without an index is a pointer to the first element

foo == &foo[0]

So if I have a pointer to an element in the array

int *p = &foo[4];

I can get the index with:

int index = p - foo;
