Could you please help to straighten things up?
A relevant line from man snprintf:
> int snprintf(char *str, size_t size, const char *format, ...);
So you might want to change line 27 to
char buf[4];
and perhaps line 62 too:
snprintf(buf,4,"%c%c%c%c",(char)0xff,0x00,0x01,0);
another relevant line from man err:
#include <err.h>
HTH, haven't tried it
