Hi Lucas, looks good, just one idea...
... > +#define BIT_U8(b) ((u8)(BIT_INPUT_CHECK(u8, b) + BIT(b))) > +#define BIT_U16(b) ((u16)(BIT_INPUT_CHECK(u16, b) + BIT(b))) > +#define BIT_U32(b) ((u32)(BIT_INPUT_CHECK(u32, b) + BIT(b))) > +#define BIT_U64(b) ((u64)(BIT_INPUT_CHECK(u64, b) + BIT(b))) considering that BIT defines are always referred to unsigned types, I would just call them #define BIT8 #define BIT16 #define BIT32 #define BIT64 what do you think?
