  156. This type is a tuple of integer and pointer.
  157. It's a generic type used as a generic descriptor, its exact meaning
  158. being defined by how it's used.
  159. Arrays of this type are passed between the OpenSSL libraries and the
  160. providers, and must be terminated with a tuple where the integer is
  161. zero and the pointer \s-1NULL.\s0
