A uint8 data type contains all whole numbers from 0 to 255. As with all unsigned numbers, the values must be non-negative. Uint8's are mostly used in graphics (colors are always non-negative).
Side note: the “uint8_t” and “int16_t” types are commonly used in C/C++ to indicate precisely what the type is, i.e. unsigned single-byte and signed double-byte in this case. They are defined in a standard C header file called “stdint. h”. A quick count tells us that this data structure uses 6 bytes of memory.
An unsigned Integer means the variable can hold only a positive value. This format specifier is used within the printf() function for printing the unsigned integer variables. printf(“%u”, value);
The difference between Uint8 and uint8_t will depend on implementation, but usually they will both be 8 bit unsigned integers. Also uint8_t and uint16_t are defined by C (and maybe C++) standard in stdint. h header, Uint8 and Uint16 are non-standard as far as I know.
I have uint8_t orig[ETH_ALEN];
How can I print it using __printf(3, 4)
which is defined as #define __printf(a, b) __attribute__((format(printf, a, b)))
the Orig should be ethernet hardware address.
