Functions
bool	stdio_init_all (void)
	Initialize all of the present standard stdio types that are linked into the binary.
bool	stdio_deinit_all (void)
	Deinitialize all of the present standard stdio types that are linked into the binary.
void	stdio_flush (void)
	Flushes any buffered output.
int	stdio_getchar_timeout_us (uint32_t timeout_us)
	Return a character from stdin if there is one available within a timeout.
static int	getchar_timeout_us (uint32_t timeout_us)
	Alias for stdio_getchar_timeout_us for backwards compatibility.
void	stdio_set_driver_enabled (stdio_driver_t *driver, bool enabled)
	Adds or removes a driver from the list of active drivers used for input/output.
void	stdio_filter_driver (stdio_driver_t *driver)
	Control limiting of output to a single driver.
void	stdio_set_translate_crlf (stdio_driver_t *driver, bool translate)
	control conversion of line feeds to carriage return on transmissions
int	stdio_putchar_raw (int c)
	putchar variant that skips any CR/LF conversion if enabled
static int	putchar_raw (int c)
	Alias for stdio_putchar_raw for backwards compatibility.
int	stdio_puts_raw (const char *s)
	puts variant that skips any CR/LF conversion if enabled
static int	puts_raw (const char *s)
	Alias for stdio_puts_raw for backwards compatibility.
void	stdio_set_chars_available_callback (void(*fn)(void *), void *param)
	get notified when there are input characters available
int	stdio_get_until (char *buf, int len, absolute_time_t until)
	Waits until a timeout to read at least one character into a buffer.
int	stdio_put_string (const char *s, int len, bool newline, bool cr_translation)
	Prints a buffer to stdout with optional newline and carriage return insertion.
int	stdio_getchar (void)
	Alias for getchar that definitely does not go thru the implementation in the standard C library even when PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS == 0.
int	stdio_putchar (int)
	Alias for putchar that definitely does not go thru the implementation in the standard C library even when PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS == 0.
int	stdio_puts (const char *s)
	Alias for puts that definitely does not go thru the implementation in the standard C library even when PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS == 0.
int	stdio_vprintf (const char *format, va_list va)
	Alias for vprintf that definitely does not go thru the implementation in the standard C library even when PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS == 0.
int	__printflike (1, 0) stdio_printf(const char *format
	Alias for printf that definitely does not go thru the implementation in the standard C library even when PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS == 0.
