I guess another complication is that some functions return
-1, which implies a signed variable. To fix all that would require a
complete rewrite of the library and probably most of the os and
applications as well, so it will never happen. Just have to write
unsigned equivalents, or slip functions with casts, but it's a lot
of additional work.

One thing I wish was available in all languages is the ability to return
multiple values from a function call so you can return both a status and
the value(s) in one assignment. Ie: "a, b, c = demo_function(param1, param2);".

In languages with dynamic associative arrays (such as PHP), I simulate

status and value fields. Makes coding _so_ much cleaner and robust.

Look at the example Arne posted. Very clean and very easy to understand
without having to use comments (and I am actually a fan of the liberal
use of comments. :-) ).

I find it rather difficult to determine WHY something is being done, just from the code.
