hb_itemGetPtr( pInfo->pNewVal ) returns pointer to structure
which holds pGT pointer:
PHB_GT * pGtPtr = ( PHB_GT * ) hb_itemGetPtr( pInfo->pNewVal );
PHB_GT pGT = *pGtPtr;
Anyhow it may change in the future so I cannot promise that
this code will work. I'd prefer to add new function:
PHB_GT hb_gt_ItemBase( PHB_ITEM pItemGT )
which can be used with hb_gt_BaseFree() in the same way as
hb_gt_Base() so your code will not be affected by possible
future modifications in internal pGT representation.
best regards,
Przemek
