I personally prefer this above an attribute. Its disputeable but I prefer to do things with "normal C constructs" where possible.

Reading this, after it had been sent, a perfect patch should make the buffer an union:

union { uint32_t ui[MAX.../4+1]; uint16_t us[MAX.../2+1]; uint8_t uc[MAX...+1]; } linebuf;

Sorry, but I do not want to see any of this /4 and /2 stuff.

Best regards,
