Hello,
What is the idea behind this two types? When to use one over another. Basically, they are the same thing:
typedef __u8 uint8_t;
In the linux kernel code I've seen both of them used without any clear rule.
thanks. Daniel.

Hello Daniel,
What is the idea behind this two types? When to use one over another. typedef __u8 uint8_t; In the linux kernel code I've seen both of them used without any clear rule.
Basically, they are the same thing. $ grep uint8_t linux/types.h typedef __u8 uint8_t; $ grep __u8 asm-i386/types.h typedef unsigned char __u8;
But you'd better use uint8_t in you kernel programming practice rather than use __u8 directly. Because asm directory varies on different architecture. The program will get better portability by using uint8_t.In an other words, uint8_t provide more abstraction for '1 byte' type.
