NAME

6       bstr_printf - Format a string from binary arguments and place it in a
7       buffer
8

SYNOPSIS

10       int bstr_printf(char * buf, size_t size, const char * fmt,
11                       const u32 * bin_buf);
12

ARGUMENTS

14       buf
15           The buffer to place the result into
16
17       size
18           The size of the buffer, including the trailing null space
19
20       fmt
21           The format string to use
22
23       bin_buf
24           Binary arguments for the format string
25

DESCRIPTION

27       This function like C99 vsnprintf, but the difference is that vsnprintf
28       gets arguments from stack, and bstr_printf gets arguments from bin_buf
29       which is a binary buffer that generated by vbin_printf.
30
31       The format follows C99 vsnprintf, but has some extensions: see
32       vsnprintf comment for details.
33
34       The return value is the number of characters which would be generated
35       for the given input, excluding the trailing '\0', as per ISO C99. If
36       you want to have the exact number of characters written into buf as
37       return value (not including the trailing '\0'), use vscnprintf. If the
38       return is greater than or equal to size, the resulting string is
39       truncated.
