Working on a Metamod plugin, I am hooking AddPlayerItem in the same way Hamsandwich does.
The function takes three arguments as below

BOOL __fastcall HookAddPlayerItem(void *pthis, int i, CBasePlayerItem *pItem)

Hooking works fine and I am able to call the original function successfully from within the hook, but I do not know how to retrieve information of pItem (ie Weapon ID, classname, etc).

I have attempted to include HLTypeConversion.h and use cbase_to_int but the returned integer does not make sense, while cbase_to_edict returns the edict pointer but I am unable to retrieve any PvPrivateData, server crashes .

Any help is appreciated.

pItem it's a class and you should understand it's hierarchy.
Check hlsdk how it work.

Here's how it's related to parent classes.
