thanks you, the A3 community finaly help me to solve the last problem
* for index := C.int(0); index < argc; index++ { out =
append(out, C.GoString(*argv)) argv =
(**C.char)(unsafe.Pointer(uintptr(unsafe.Pointer(argv)) + offset)) }*
I dont really understand why but it seems there was a problem with my
casting method with unsafe
*(*int)(unsafe.Pointer(limit)
