Hi,  Yulong

I have one question about the following function:

+static uint16_t get_unaligned_le16(const void *p) {
+    uint16_t value;
+    memcpy(&value, p, sizeof(uint16_t));
+    return value;
+}

Is this for handling the data under a little-endian machine? It might have a different result when calling the above function on a big-endian/little-endian machine, is that expected behavior? Just confirm with you.

Thanks

Lianbo
