4370aa4a Lai Jiangshan 2009-03-06 2391 * This function like C99 vsnprintf, but the difference is that vsnprintf gets
4370aa4a Lai Jiangshan 2009-03-06 2392 * arguments from stack, and bstr_printf gets arguments from @bin_buf which is
4370aa4a Lai Jiangshan 2009-03-06 2393 * a binary buffer that generated by vbin_printf.

4370aa4a Lai Jiangshan 2009-03-06 2395 * The format follows C99 vsnprintf, but has some extensions:

4370aa4a Lai Jiangshan 2009-03-06 2397 *
4370aa4a Lai Jiangshan 2009-03-06 2398 * The return value is the number of characters which would
4370aa4a Lai Jiangshan 2009-03-06 2399 * be generated for the given input, excluding the trailing
4370aa4a Lai Jiangshan 2009-03-06 2400 * '\0', as per ISO C99. If you want to have the exact
4370aa4a Lai Jiangshan 2009-03-06 2401 * number of characters written into @buf as return value
4370aa4a Lai Jiangshan 2009-03-06 2402 * (not including the trailing '\0'), use vscnprintf(). If the
4370aa4a Lai Jiangshan 2009-03-06 2403 * return is greater than or equal to @size, the resulting
4370aa4a Lai Jiangshan 2009-03-06 2404 * string is truncated.
