NAME
       bstr_printf - Format a string from binary arguments and place it in a buffer

SYNOPSIS
       int bstr_printf(char * buf, size_t size, const char * fmt, const u32 * bin_buf);

ARGUMENTS
       buf
	   The buffer to place the result into

       size
	   The size of the buffer, including the trailing null space

       fmt
	   The format string to use

       bin_buf
	   Binary arguments for the format string

DESCRIPTION
       This function like C99 vsnprintf, but the difference is that vsnprintf gets arguments from stack, and bstr_printf gets arguments from
       bin_buf which is a binary buffer that generated by vbin_printf.

       The format follows C99 vsnprintf, but has some extensions: see vsnprintf comment for details.

       The return value is the number of characters which would be generated for the given input, excluding the trailing '', as per ISO C99. If
       you want to have the exact number of characters written into buf as return value (not including the trailing ''), use vscnprintf. If the
       return is greater than or equal to size, the resulting string is truncated.
