Mac STRING_GetStringLength: char* __fastcc (char* szDest ECX, char* szText EDX, uint32_t* pTotalLength)

checked · by KierTaylor · submitted 2026-11-08

Resubmit of #1309 (approved, then stale because __fastcall is not defined on Mac), now with __fastcc. ECX -> ESI = destination, EDX -> EDI = source, [EBP+8] = pointer to the running length. It returns szDest+strlen+1. Caller 0x002cd1ef. Windows twin 0x0044a170.
