| Wouldn't the documentation for whatever this is tell you what the parameters are? Or a forum with people who actually use this library? The probability of finding a user of this library on this site seems low. |

Those are bitmasks. They're being put in the inout parameter and then binary or'ed with a bunch of other stuff. They set a particular bit in the output, which marks whether we're doing a 'copy out' or a 'copy in', whatever those are. You should definitely look up bitwise operators if you're going to do much low level C stuff.

I'm guessing you're going to actually run this stuff within a BSD of some description? If so, why not use the provided interfaces, why try to bitbang the registers on a device by hand while running within BSD? |
