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.
