*  Name:
*     dat1ExportDims

*  Purpose:
*     Export dimensions from HDF5 to HDS form

*  Language:
*     Starlink ANSI C

*  Type of Module:
*     Library routine

*  Invocation:
*     void dat1ExportDims( int ndims, const hsize_t h5dims[], hdsdim hdsdims[],
*                          int * status );

*  Arguments:
*     ndims = int (Given)
*        Number of dimensions to export.
*     h5dims = const hsize_t [] (Given)
*        HDF5 Dimensions to import. Only ndims will be accessed.
*     hdsdims = hdsdim[] (Returned)
*        Array to receive imported dimensions. Must be at least ndims in size.
*     status = int* (Given and Returned)
*        Pointer to global status.

*  Description:
*     Export the dimensions in HDF5 form and convert them to the dimensions
*     suitable for use in caller code that is assuming HDS compatibility.

*  Authors:
*     TIMJ: Tim Jenness (Cornell)
*     {enter_new_authors_here}

*  Notes:
*     - Does not assume that hdsdim and hsize_t are the same type.
*     - Transposes the order as HDS uses Fortran order and HDF5 uses
*       C order.

*  History:
*     2014-09-03 (TIMJ):
