Functions
static void	string_writer_init (string_writer_t *sw, void *buffer, size_t len)
	Initialize a string writer structure.
static size_t	string_writer_len (const string_writer_t *sw)
	Get the size of the string contained by the string writer.
static const char *	string_writer_str (const string_writer_t *sw)
	Get the string contained by the string writer.
int	__swprintf (string_writer_t *sw, FLASH_ATTR const char *restrict format,...)
	Write a formatted string to a buffer The string will be truncated if there is not enough space left in the destination buffer.
static void	explicit_bzero (void *dest, size_t n_bytes)
	Like memset(dest, 0, n_bytes), but secure.
ssize_t	strscpy (char *dest, const char *src, size_t count)
	Copy the string, or as much of it as fits, into the dest buffer.
const void *	memchk (const void *data, uint8_t c, size_t len)
	Check if the entire buffer is filled with the same byte.
