I prefer a space between the number and the postfix (if a postfix is present), e.g. "1.23 M", so when followed by the unit, it becomes "1.23 Mbit/s" rather than "1.23M bit/s". > +/** > + * Converts the uint64_t value provided to a human-readable string. > + * It null-terminates the string, truncating the data if needed. Please add some examples showing the output formatting. E.g.: "123 M", "12.3 M", "12 M", " 12 M" or "12.0 M", "1.00 ", " 1.00", or " 1", or something else? > + * > + * @param buf > + * Buffer to write the string to. > + * @param buf_size > + * Size of the buffer. > + * @param count > + * Number to convert. > + * @param use_iec > + * If true, use IEC units (1024-based), otherwise use SI units > (1000-based). > + * @return > + * Number of characters written (not including the null- > terminator), > + * or that would have been required when the buffer is too small. > + */ > +int > +rte_size_to_str(char *buf, int buf_size, > + uint64_t count, bool use_iec); > +
