How can the Arduino know how long an array is? I need to pass an array (actually a pointer to an array) to a function, and the function needs to be able to determine how many elements the array contains. I think I want something like strlen, but for a uint8_t array (no NULL character guaranteed).

Thanks for the reply.

Neither of those are ideal, but probably possible.

Are there other options?
