Returns the array of bit converted to an int. The conversion is based of endianness value.
Converts up to the first 32 bits of the array to \c uint32_t and returns it,
obeying \a endianness. If the array has more than 32 bits, \a ok is set to false
and this function returns zero; otherwise, it's set to true.
