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

size

fmt

bin_buf

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 '\0', as per ISO C99. If you want to have the exact number of characters written into buf as return value (not including the trailing '\0'), use vscnprintf. If the return is greater than or equal to size, the resulting string is truncated.
