Copy len bytes of data from the contiguous chunk of memory
pointed to by buf into the buffer exported by obj. Return
0 on success and return -1 and raise a PyBuffer_Error on
error (i.e. the object does not have a buffer interface or
it is not working).
If fort is 'F' and the object is multi-dimensional,
then the data will be copied into the array in
Fortran-style (first dimension varies the fastest). If
fort is 'C', then the data will be copied into the array
in C-style (last dimension varies the fastest). If fort
is 'A', then it does not matter and the copy will be made
in whatever way is more efficient.
