Mac COMCALLBACK_CreateChannelUser: uint8_t __fastcc (pUser ECX, uint8_t* pRawData EDX, nStatusFlags)

checked · by KierTaylor · submitted 2026-11-08

Resubmit of #1316 (approved, then stale because __fastcall is not defined on Mac), now with __fastcc. ECX -> ESI = channel user, EDX -> EDI = raw stat-string, [EBP+8] = status flags. It returns the class byte (MOVZX EAX,BL at 0x002d7290). The caller 0x002d5e1e keeps AL. Windows twin 0x00446d90.
