It might have sense to compare return code not with 0, but
sizeof(upath), since "... The functions snprintf() and vsnprintf() do
not write more than size bytes (including the terminating null byte
('\0')). If the output was truncated due to this limit then the return
value is the number of characters (excluding the terminating null
byte) which would have been written to the final string if enough
space had been available. Thus, a return value of size or more means
that the output was truncated. ..."
