I need using some user data (like ItemIndex, ItemType, Attribute...etc)which linked to an entity. Now I get the Entity's pointer, how can I access those data?

I try to do this:
Using a struct collect the values,
Code:
typedef struct Item
{
    int iIndex;
    int iType;
    int iMaxEffection;
    int iMinEffection;
    int iEquipLimit;
    ...
    STRING *pszItemName;
    STRING *pszItmeText;
    ENTITY *pItemEnt;
}T_Item;

and then create a Item implementation in game,
use c_trace get the target pointer what I touched,
now I want to show the target name, how can I using the pointer(T_Item->pItemEnt) to get other struct members (T_Item->pszItemName)?

Thanks to read.
