Get array of raw pointers from array of std::unique_ptr

Question

I have a library function that requires an array of four pointers as parameter: f(unsigned char* data[4]), and I have an array of smart pointers in my code: std::unique_ptr<unsigned char> myArray[4].

Is there a way to use the smart pointers with this library function ?

I have already tried this but it gives me a segfault: f(reinterpret_cast<unsigned char **>(myArray[0].get()));

Answer 1

std::array<unsigned char* , 4> arr = { myArray[0].get(),myArray[1].get(),myArray[2].get(),myArray[3].get() };

pass arr.data().
