Standard Integer Types

---

Detailed Description

 #include <stdint.h> 

Use [u]intN_t if you need exactly N bits.

Since these typedefs are mandated by the C99 standard, they are preferred over rolling your own typedefs.

Note:

If avr-gcc's -mint8 option is used, no 32-bit types will be available for all versions of GCC below 3.5.

8-bit types.
typedef signed char	int8_t
typedef unsigned char	uint8_t
16-bit types.
typedef int	int16_t
typedef unsigned int	uint16_t
32-bit types.
typedef long	int32_t
typedef unsigned long	uint32_t
64-bit types.
typedef long long	int64_t
typedef unsigned long long	uint64_t
Pointer types.
These allow you to declare variables of the same size as a pointer.
typedef int16_t	intptr_t
typedef uint16_t	uintptr_t
