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
this by returning an associative array from a function call with both
status and value fields. Makes coding _so_ much cleaner and robust.

Few languages support multiple return values.

Nonsense.  _Many_ languages do; just not ones that you are
familiar with.

And a few other languages support tuples with named fields
or anonymous classes with named properties, which is almost as good.

See above.

And almost all newer high level languages support
map/dictionary/associative array.

What does this even mean?  Many of these things have been
supported by high(er)-level languages for decades.  Perhaps
you mean as a first-class object in the language, and not
simply via a library?
