The sole parameter pClient is the game client: the body reads a pending unit count at +0x3bc and the 9-byte unit records starting at +0x1cc, both inside D2ClientStrc.nPacketBuffer (456..959) in the Mac database, and passes the same pointer to CLIENTS_PacketDataList_GetHead to find the client's outgoing packet buffer. The offsets are not named D2ClientStrc fields, so the evidence is that region membership and the parameter name/role, not a named field. No Windows twin. Same-width retype; name kept. Mac callers were not traced.
