i found another thing.
func RVExtensionArgs(output *C.char, outputsize C.size_t, input *C.char,
argv **C.char, argc C.int) {
var offset = unsafe.Sizeof(uintptr(0))
var out []string
* limit := *(*int)(unsafe.Pointer(&argc)) if limit < 1000 {
for index := 0; index < limit; index++ { out = append(out,
C.GoString(*argv)) argv =
(**C.char)(unsafe.Pointer(uintptr(unsafe.Pointer(argv)) + offset))
} }*
temp := fmt.Sprintf("Hello %s %d %s!", C.GoString(input), limit, out)
// Return a result to Arma
result := C.CString(temp)
defer C.free(unsafe.Pointer(result))
var size = C.strlen(result) + 1
if size > outputsize {
size = outputsize
}
C.memmove(unsafe.Pointer(output), unsafe.Pointer(result), size)
}Saisissez le code ici...
it seems there is also a bug in the main program cause the argc variable,
the first execution time contains a memory adress instead of int
