struct PK_LBALL_ask_lrods_r_s
    {
    int         r_t_version;    --- version number of return structure
    int         n_lrods;        --- number of lrods
    PK_LROD_t  *lrods;          --- the lrods
    };
typedef struct PK_LBALL_ask_lrods_r_s PK_LBALL_ask_lrods_r_t;


A structure packaging the lrods with 'lball' as one of their lballs.

Used in:

PK_LBALL_ask_lrods
PK_LBALL_ask_lrods_r_f

The structure has the following fields:

'n_lrods'     The number of lrods.

'lrods'       An array of length 'n_lrods', each element holding an lrod.

The output array 'lrods' is optional.  If the option 'want_lrods' is set to
PK_LOGICAL_false, the function will only compute the number of lrods which have
this lball as one of their lballs.

The function PK_LBALL_ask_lrod_r_f may be used to free associated memory.
