Just pointing out a few style issues: - The function name does not need to be duplicated in the comment - For function documentation, we usually use the following format: /*! This function is meaningless. I only wrote it because I can. */ int path_to_greatness(int me) { return me + 1; }Note that there is no blank line between the doxygen comment and the function.

Prefer to put each on its own line.
+ switch((result >> 12) & 0xf) {
Space between 'switch' and '('.

Only the file's counterpart header should be first to make sure the header is self contained.

DS/DA aren't good names (but I assume this code will be removed anyway again).
