.. c:function:: int PyBuffer_ToContiguous(void *buf, Py_buffer *src, Py_ssize_t len, char order)
Copy *len* bytes from *src* to its contiguous representation in *buf*.
- *order* can be ``'C'`` or ``'F'`` (for C-style or Fortran-style ordering).
- ``0`` is returned on success, ``-1`` on error.
+ *order* can be ``'C'`` or ``'F'`` or ``'A'`` (for C-style or Fortran-style
+ ordering or either one). ``0`` is returned on success, ``-1`` on error.
This function fails if *len* != *src->len*.
