*  Name:
*     dat1SetAttHdsdims

*  Purpose:
*     Store HDS dimensions array in an HDF5 attribute

*  Language:
*     Starlink ANSI C

*  Type of Module:
*     Library routine

*  Invocation:
*     dat1SetAttrHdsdims( hid_t obj_id, const char * attrname,
*                         int nvals, const hdsdim_t values[], int * status );

*  Arguments:
*     obj_id = hid_t (Given)
*        HDF5 object to associate with attribute.
*     attrname = const char * (Given)
*        Name of attribute.
*     nvals = int (Given)
*        Number of values. Can not exceed DAT__MXDIM.
*     values = const hdsdim_t [] (Given)
*        Values to store in attribute.
*     status = int* (Given and Returned)
*        Pointer to global status.

*  Description:
*     Store an array of hdsdim integers in an attribute associated
*     with the specified HDF5 object.
