On a second note, why is '\n' needed there? You should only need '\0', as a '\n'

at the end is not required by any of the string functions used to convert the address. I believe you could go with buf[RPCBIND_MAXUADDRLEN+1] for the extra NUL only.

AFAICT, strict_strtoul() requires the '\n\0' termination.
