Hello. Is there a difference between u32 to __u32 ? (I didn't see any in the source). Maybe There is a best convention which to use ? should I use u32 or __u32 ? (I need data types that will be fixed in size no matter the platform, for extracting data from binary structures) and what are __le16 and __be16 ? they seems to be the same. they use __attribute__((bitwise)). what is this attribute ?
