BSTR_PRINTF(9) Basic C Library Functions BSTR_PRINTF(9)NAMEbstr_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 ´\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.
