bstr_printf — Format a string from binary arguments and place it in a buffer
int bstr_printf ( | char * buf, |
| size_t size, | |
| const char * fmt, | |
const u32 * bin_buf); |
bufThe buffer to place the result into
sizeThe size of the buffer, including the trailing null space
fmtThe format string to use
bin_bufBinary arguments for the format string
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.
