I'd put this right before the bytes_left -= bytes. Also, buf is a void *. That makes pointer arithmetic on it somewhat undefined. From what I can find, GCC supports it as an extension. See also https://stackoverflow.com/questions/3523145/pointer-arithmetic-for-void-pointer-in-c. If it compiles without a warning, I guess it's OK as is.
