-
-   Copy *len* bytes of data pointed to by the contiguous chunk of memory
-   pointed to by *buf* into the buffer exported by obj.  The buffer must of
-   course be writable.  Return 0 on success and return -1 and raise an error
-   on failure.  If the object does not have a writable buffer, then an error
-   is raised.  If *fortran* is ``'F'``, then if the object is
-   multi-dimensional, then the data will be copied into the array in
-   Fortran-style (first dimension varies the fastest).  If *fortran* is
-   ``'C'``, then the data will be copied into the array in C-style (last
-   dimension varies the fastest).  If *fortran* is ``'A'``, then it does not
-   matter and the copy will be made in whatever way is more efficient.
